The Journal of the Brazilian Chemical Society (JBCS) embraces all aspects of chemistry except education, philosophy and history. It is a medium for reporting selected original and significant contributions to new chemical knowledge. The Journal publishes Full Papers, Communications, Reviews, Accounts, Perspectives and Comments/Reply to Comments.
The reproduction of figures, schemes and photos already published in other publications, even if these materials have been published by the same authors, requires the copyright permission given by the editor house allowing the publication of the article in the JBCS .
For materials (figures, schemes, etc.) under CC-BY license, the copyright permission is not necessary, and the author must include in the manuscript the credits (attribution), see the example:
Figure 1. A binary phase diagram for eutectic mixture formation (figure from reference 12 with CC-BY attribution).
Full Papers
Full Papers articles provide detailed and critical analyses of significant problem-solving endeavors, offering comprehensive insights into original research. Full papers are expected to deliver thorough accounts of innovative studies in chemistry, featuring substantial scope and appeal to a broad and diverse audience. Submissions that build upon prior work, such as preliminary letters or communications, are both encouraged and welcomed, provided they demonstrate a meaningful expansion or substantial advancement of the initial findings. These contributions should go beyond merely including additional experimental details or examples, incorporating new experimental methods, supplementary data, in-depth discussions, and expanded conclusions. Shorter contributions are better suited for submission as Communications.
Communications
A Communication serves as a concise and swift platform for presenting the most critical aspects of a study. It is designed to provide a brief yet impactful disclosure of new findings, offering sufficient background information to contextualize the research while justifying the need for a rapid publication format. This article type is intended for disseminating urgent and groundbreaking discoveries of exceptional importance, particularly those that capture the interest of specialists in the field while remaining relevant to the journal's diverse chemistry readership. As a general guideline, Communications are typically no more than 5 pages in the journal's finalized layout.
Reviews
Reviews are generally solicited by the Editors; however, the JBCS welcomes submissions from all branches of the chemical sciences. Such reviews should capture the interest of the journal’s diverse readership by providing a timely and valuable contribution to the field. A successful review must critically assess the current state of the subject, highlight its relevance, and justify the necessity of the review within the existing literature. Additionally, it should propose future directions for research, offering meaningful insights and recommendations. Review articles must not include unpublished research and should feature carefully selected references that provide a balanced perspective.
While Reviews are typically submitted by invitation, the Editors encourage prospective authors to propose suitable topics via email at help_office@jbcs.sbq.org.br. Proposals must adhere to the mandatory template available on the journal’s website. Any unsolicited Reviews that have not been invited or pre-approved by the Editors will not be considered for publication. The acceptance of a synopsis for a proposed review does not guarantee the publication of the final manuscript.
Accounts
Accounts feature concise, focused articles that provide clear and accessible overviews of fundamental research and its applications across all areas of chemistry, as well as related fields where chemical approaches are central. Each article highlights research conducted by the author’s own laboratory, aiming to educate readers about specific projects. Submissions exploring newly emerging areas of research are particularly encouraged.
Although Accounts are typically invited, the Editors welcome proposals for potential topics. Prospective authors should submit their proposals via email to help_office@jbcs.sbq.org.br using the mandatory template provided on the journal’s website. Unsolicited submissions that have not been invited or approved in advance will not be considered. It is important to note that the acceptance of a synopsis for a proposed Account does not ensure the publication of the final manuscript.
Perspectives
Perspectives are authored by recognized experts and provide personal insights into specialized areas of research. These articles are published exclusively by invitation from the Editor-in-Chief (the JBCS Coordinator). Specific guidelines and requirements will be communicated directly to the invited authors.
Comments/Reply to Comments
Comments (and their corresponding replies) serve as a platform for the exchange of scientific opinions and discussions between authors and readers regarding content published in the JBCS. To be considered for publication, a comment should offer either an alternative analysis or fresh insights into the previously published material. Replies to comments should aim to advance the discussion initiated by the original article and the comment. It is important to note that comments or replies containing personal attacks are strictly unsuitable for publication. Comments that are acceptable for publication will be forwarded to the authors of the work being discussed, and these authors will be given the opportunity to submit a Reply. The Comment and Reply will both be subject to rigorous peer review in consultation with the journal’s Editorial Board where appropriate. The Comment and Reply will be published together.
See JBCS Ethical Guides and Publication Copyright in our webpage: http://jbcs.sbq.org.br/ethical_guides
The authenticated ORCID iD is required for the submitting agent. For those that do not have an ORCID identifier, the ScholarOne submission system is integrated to the ORCID .gif)
website, and an account can be easily created during the submission process.
The ScholarOne-JBCS submission system is configured to use the CASRAI’s CRediT taxonomy to recognize the individual contributions of authors ( containing 14 roles), being a required item to the accomplishment of the submission. When adding authors to the submission, you will choose from a list of contributions. Check the author’s role options, then select the level of contribution from the dropdown.
The 14 roles according to the CASRAI’s CRediT taxonomy are: Conceptualization, Data curation, Formal analysis funding acquisition, Investigation, Project administration, Resources, Software, Validation, Visualization, Writing original draft and Writing-review & editing
The levels of contribution: Lead, Support, Equal
For manuscript with 6 or more authors, the JBCS requires the specification of the individual contribution of each author in the text. This information, according to the 14 roles from the CASRAI’s CRediT taxonomy, may be added before the Reference, named as Author Contributions, see template.
The JBCS adopts the use of the anti-plagiarism Tool iThenticate since the end of 2015.
Authors should present their materials with the utmost conciseness and clarity. The Introduction should clearly and briefly identify, with relevant references, both the nature of the problem under investigation and its background. Extensive reviews of the literature cannot be accepted.
In Full Papers, the Experimental section may precede or follow the Results and Discussion section, but should be separated from it. The addition of a final section at the end of the manuscript, which briefly summarizes the main Conclusions of the work, is recommended and needs to be just after the Results and Discussion section.
Descriptions of experiments should be given in sufficient details to enable other researchers to repeat them. The degree of purity of materials should be given, as well as all quantities used. Descriptions of established procedures are unnecessary. Standard techniques and methods used throughout the work should be stated at the beginning of the section in a Materials and/or Methods subsection, in the Experimental section. Apparatus should be described only if it is non-standard. Commercially available instruments should be referred to by their suppliers and models.
All new compounds should be fully characterized, which includes spectroscopic data and elemental analyses. High-resolution mass spectra may substitute for elemental analyses if accompanied by unequivocal proof of sample purity (melting points, copies of NMR spectra, etc.). For compounds prepared in enantiomerically pure or enantiomerically enriched form, specific optical rotation must be given. In cases where enantiomeric excess is determined by chromatographic and/or spectroscopic techniques, copies of the appropriate chromatograms and/or spectra should be included as Supplementary Information upon submission of the manuscript. Data associated with specific compounds should be listed after the name of the compound concerned, followed by the description of the preparation, or else presented in tabular form in the Results and Discussion section. All spectra must be included in the Supplementary Information (SI, see Section 8).
Many theoretical and computational papers use a routine procedure based on a well-documented method, being it semi-empirical or ab initio. It is then sufficient to name the particular variant, referring to key papers, in which the method has been developed, to cite the computer program used and to indicate briefly any modification made by the author.
Complementary data meant to support the analysis of Communications should be included as Supplementary Information (SI, see Section 8).
It is the authors' responsibility to obtain permission from other publishers for the reproduction of artwork from other journals in the reviews or in any other type of publication. Such specific Copyright Permissions should be sent to the JBCS Editorial Manager. Suitable acknowledgement of reproduction must be given in the captions.
JBCS is committed to advancing scientific communication and supports the positive impact of AI tools when used responsibly. We encourage authors to leverage these technologies to enhance their manuscripts while maintaining ethical standards and transparency. Together, we can foster a progressive scientific community that embraces innovation in research and publication practices.

-
Sub-Sections: first initial with capital letter, no final full stop . Examples:
Reagents and equipments
X-ray data
-
Formulae (compounds): should be numbered with bold Arabic numerals.
-
Structural or displayed formulae must be accurately drawn and inserted in the text. All captions should be typed below the structural or displayed formulae, together with it, in the right position.
General Size
The authors should think about the illustration size for double column (172 mm) of the journal. But, the font type size of text must be consistent with the illustration since it can be reduced during preparation of the Galley Proof.
This is important when choosing symbols for graphics, drawings, charts, photos, etc., be consistent, make your manuscript look nicer: use the same size and same font type in graphics, schemes, etc.
Lines and Lettering: Lines should be black and of an adequate and even thickness. Solid, broke, dotted and dot-dash lines should be used in graphics. Particular care should be taken to ensure that the lines in a spectrum are of adequate thickness.
Lettering should not be smaller than 7 pt (Times New Roman) and lines not thinner than 0.5 pt. Lettering and lines should be of uniform density throughout the figures.
Labeled atoms in ORTEP (or any other) diagrams should have atom numbers in parenthesis, e.g., Fe(1), C(44).
Symbols representing physical quantities should be given in italics, e.g., J (Hz), δ (ppm), m/z, etc.
Units should be expressed in the appropriate form, e.g., g cm -3 or mol L -1, rather than g/cm 3 or mol/L (see Section 4.4)
Graphs
- Scales: graphs should have only the minimum necessary scale divisions marked by numerals.
- Axis labels should use SI units, separated from quantities (see details in the green book
https://iupac.org/projects/project-details/?project_nr=110-2-81 or http://www.sbq.org.br/livroverde/):
For graphs, use slashes in X and Y axes to separate axes names from units. For example: 2θ / degree; Temperature / oC; time / min; Size range / mm; Wavenumber / cm -1. Use parentheses only to group a set of units, e.g., Concentration / (mol L -1) ; 10 3 (T/K) -1, etc.
Pay close attention to the way decimal values are expressed in English. Employ dots instead of commas.
Figures must have a high quality in order to be well reproduced. Use at least a 900 dpi resolution. If necessary, resize to a smaller size to get higher quality.
Curves should be labeled (a), (b), (c) etc. and further information be given in the figure legend/caption.
Data Points must be shown sufficiently large to be distinguishable. Whenever possible, they should be marked
with the following symbols (use alternated full and open symbols):
●, ○, ■, □, ▲, Δ, ♦, ◊
Graphs/Figures should be pasted from their original files (Origin, ChemDraw, Corel etc.) and have an excellent
quality. If you have to digitalize (scan) the figures (photos, for instance), choose the following scan options: black & white (B&W), no background and minimum of 300 dpi. If you wish them to be published online in color, send both the colored and B&W versions to the Editorial Office, matching the captions of the figures to accommodate the alternatives.
For computer-generated artwork, background or shadings should be avoided.
Figures, schemes and structures should be drawn to fit single or double-column widths. They should look proportional in case they are reduced.
Structures should be numbered with bold Arabic numerals, e.g., 1, 2.
All chemical structures included in the manuscript should be drawn using the same letter type (Times New Roman or Arial), size of cyclic groups, size and thickness of chemical bonds, and, the most important, authors should use the same standard throughout the work, including all figures, schemes, etc.
The following organic group abbreviations may be used: Me, Et, nPr, nBu, sBu, tBu, Ph, CO 2R, CO 2H, iPrOH.
One variable univalent substituent is indicated by R. When more than one independent variable general substituent is present, R 1, R 2, R 3, etc. should be used.
A variable metal may be indicated by M and variable ligands by L 1, L 2, L 3 or L1, L2, L3, etc.
Photographs should be highly contrasted, positive and not mounted.
When necessary, the scale should be drawn on the photograph itself and not below.
Color prints are rarely reproduced satisfactorily in black and white. Original B&W photographs are preferred to report experimental results, such as electron micrographs or to illustrate special equipment adaptations.
Tables
Format your table to give straightforward information to the reader. Do not use shades or bold lettering. Indicate any extra information as a footnote with letters, e.g., a, b, c, etc. For examples, see any "PDF" files in: http://jbcs.sbq.org.br/forthcoming_papers.asp.
Data
For negative numbers, ions and equations in text and tables use − (negative symbol) instead of - (hyphen). Examples: Cl −, −0.40, y=a x − b.
Units
Use International System Units (SI), e.g., m, s, kg, Pa, mol L -1, etc, separated from quantities with a blank space. Example: 300 K, not 300K. See: https://iupac.org/what-we-do/books/color-books/.
Note: IUPAC convention recommends to avoid the unit Molar (M), being suggested mol L -1 or mol dm -3, with consistent use throughout your manuscript.
For examples, see any "PDF" files in: http://jbcs.sbq.org.br/forthcoming_papers.asp
Concerning the JBCS Table of Contents, it is expected from authors careful with their Graphical Abstract (GA) proposition. This image is the one used in the JBCS posts in the social media (Facebook and Instagram) and index, so it is very important to propose a creative figure summarizing the work, and the resolution is fundamental.
This way, the figure should summarize the content of the manuscript in a concise, pictorial form, designed to capture the attention of a wide readership. The author should present a new figure, using as an idea a key structure, a reaction, an equation, a concept, a graphic, a theorem, etc. It should be used colors as much as possible and have an artistic and imaginative idea. Short movies are also welcome (as supplementary information (SI)). It is not acceptable photos of commercial equipment in GA or in the text of the manuscripts.
Pay Attention: the image should have a 900 dpi resolution (*.tiff / *.jpg or any other image file that can be edited and be 8 cm wide and 4 cm high). Along with the GA figure, insert a short explanatory text about it below (three lines at the most).
Take a look at our recent publications whose Table of Contents presents Graphical Abstracts (http://jbcs.sbq.org.br). Therefore, be smart to advertise your manuscript, send a beautiful and appealing graphical image.
When writing equations, use the Word editing equation option or any other equation editor. Equation cannot be added in the main text as image format.
Citations should be typed just after punctuation (without space) as superscripts, see the example:
example 1: … of the environment.1-8 A behavior… {1-8 as superscripts}
INSTEAD OF: … of the environment, 1-8. A behavior… {1-8 as superscripts}
INSTEAD OF: … of the environment. 1-8 A behavior… {1-8 as superscripts}
Authors are responsible for the accuracy and completeness of all references.
-> Attention to punctuations “,”, “;”, “.”, and upper and lowercases, and upper and lowercases - they are also important in the format of references.
-> Numbering format of the reference list is in arabic followed by dot:

This material will be available online in the JBCS Page as PDF file. It should contain relevant and complementary data to those presented in the manuscript. Their format can be: tables, graphs, spectra, films and so on.
Any synthesized or identified compound must be accompanied by the spectra used for such identification. This is especially important for Natural Products, Organic and Inorganic Chemistry manuscripts in which the characterization/identification techniques are part of the work.
Deposition of Crystallographic Data
Prior to the submission of the typescript including crystallographic data, the author(s) should deposit, in the relevant Data Center, the data corresponding to each structure to be reported.
Data for organometallic, organic, coordination (Werner-type) and inorganic compounds should be sent to the joint CCDC/FIZ Karlsruhe online deposition service (https://www.ccdc.cam.ac.uk/Community/depositastructure/), in CIF format. More information about the deposit can be obtained from the CCDC/FIZ Frequently Asked Questions (FAQ) homepage: https://www.ccdc.cam.ac.uk/support-and-resources/Support/search?c=d738a58f-c4ab-49f3-95af-569f2fe5d2f9.
CCDC: Cambridge Crystallographic Data Centre (https://www.ccdc.cam.ac.uk/) FIZ: Fachinformationszentrum (https://www.fiz-karlsruhe.de/).
Deposition Codes
The Data Centers will provide deposition codes for each data set, which should be quoted in the typescript under a Supplementary Information heading before the Acknowledgements.
Standard text for CCDC:
Crystallographic data (excluding structure factors) for the structures in this work were deposited in the Cambridge Crystallographic Data Centre as supplementary publication number CCDC XXXXXX. Copies of the data can be obtained, free of charge, via https://www.ccdc.cam.ac.uk/structures/.
CheckCIF
During submission of a manuscript to the Journal of the Brazilian Chemical Society, authors should provide CCDC/FIZ reference numbers as Supplementary Information according to the instructions given above. CIF files should not be submitted with the manuscript (only to the suitable Data Center). Any revised CIF generated during the editorial process should be deposited directly with the CCDC before the revised manuscript is submitted to the JBCS.
During submission, authors are required to provide a checkCIF report for their crystal data together with the manuscript files. This report can be obtained via the free checkCIF service (https://checkcif.iucr.org/) provided by the International Union of Crystallography (IUCr, https://www.iucr.org/). Any occurrence that produces ‘level A’ and ‘level B’ alerts in the checkCIF should be dealt with in the manuscript or well justified before acceptance of the manuscript can be considered.
Preparation of Crystallographic Material
When the manuscript is submitted, the following guidelines should be observed:
The Abstract should not contain crystal data, but a concise statement of the main features of the structural results.
The following crystallographic data should be given in a paragraph of a Table, in a concise format:
9.1.1 Color, habit and size of the crystal(s) used, behavior of the compound under the data collection conditions.
9.1.2 The chemical formula should correspond to the complete chemical unit encompassing the crystallographic
symmetry, the formula weight, F(000), the absorption coefficient and the measured and calculated densities.
9.1.3 The unit cell parameters with esd's and the X-ray wavelength used.
9.1.4 The crystal system, space group and number of chemical units per cell.
9.1.5 Type of diffractometer used and method of data collection, total number of data collected, number of
unique reflections, R(int) value, number of observed reflections with cut-off parameter, use or not of absorption correction, transmission factors.
9.1.6 The final results: R, wR, S and the number of parameters refined; treatment of hydrogen atoms; final peak
and hole in the last difference map. Only refinements on F2 will be accepted.
Discussion of the Structure
It must include a labeled diagram of the structure, a list of relevant geometric parameters - interatomic bond distances and angles, torsion angles, hydrogen bond parameters, etc. Data of less important parts of the structure, such as ligand sub-groups (phenyl rings, etc.) should be omitted.
Whenever a compound is synthesized or identified (new or already known), it is imperative to send all spectral data (data and spectra) as Supplementary Information (SI) along with your submission, at the end of your doc file.
A brief mention to the existence of complementary data should be included in the Supplementary Information topic before the Acknowledgments section. Example:
Supplementary Information
Supplementary information (Figure S1-S4, Table S1) is available free of charge at http://jbcs.org.br as PDF file.
How to send this type of information:
Join all spectra in one SI file. Do not forget to add captions to each one of them, identifying each individual spectrum (e.g., Figure S1. 1H NMR Spectrum of...; Figure S2. IR Spectrum of...; Figure S3. 13C{1H}Spectrum of...; Table S1. Data for…). If the spectra will be digitalized (scanned), choose options: black&white, without background and 300 dpi at least. Add this file to the end of your manuscript, which should then comprehend one single doc file, containing GA, text with tables and figures, and SI.
The JBCS submission offers only online submission. The submissions are made using the ScholarOne TR-
JBCS system by clicking the link “Submission online (ScholarOne)” at our website ( http://mc04.manuscriptcentral.com/jbchs-scielo).
-
All the authors must have their names introduced in the platform, so fill this part and inform the correct co-authors’
e-mail addresses in the system.
-
In the ScholarOne-JBCS system, all files need to be uploaded individually:
(i) Main manuscript: as full.doc, not as full.pdf and
(ii) Figures/Schemes (just the ones from the main document), including GA image: as jpg, tiff, opj, xls, etc (not as individual doc files or grouped in a doc file).
Figures built using Excel/Origin programs provide pictures higher quality in the final work (proof), so upload preferentially original xls/opj files.
• In the main document (full.doc): also keep tables/figures/schemes/equations and their legends as close as possible of their first citation.
In cases that the manuscript has already received a decision from JBCS Editor like Reject&Resubmission some specific requirements are necessary:
(1) Main document: the modifications need to be highlighted with a different color guiding Editor/Reviewers with changes made in relation to the original version (do not use the track changes mode in MS Word).
(2) Be sure that the Response Letter, in the place of the cover letter, itemizes each comment addressed, as well as any changes made, of all Referee(s) and Editor (if so). Write a very convincing text explaining the points that were introduced/removed, new experiments that were used. Add, please: “Response Letter for ID JBCHS-201x-0xxx (previous ID ): ...”
(3) Replace all the files that were modified uploading with the new files.
For Reject&Resubmission decision, Authors may access the previous ID (one that received the decision) in
the Author Center at the JBCS-ScholarOne submission site (http://mc04.manuscriptcentral.com/jbchs-scielo at the link "Manuscripts with Decisions") and then in "create a resubmission" to resubmit the manuscript.
With the resubmission, the manuscript will receive a new ID. The use of this link will accelerate the evaluation since the system will keep all the decisions for the previous ID linked to the new ID.
All these actions for an already evaluated manuscript will expedite the assessment.
The JBCS Journal Publishing Staff will contact you in the near future regarding your manuscript page proofs (GP).
The proofs are provided for the correction of printing errors only, i.e.,the proof correction should not be used for language or content improvement. If considered excessive, the change costs will be charged to the author(s).
Corrected galley proofs should be returned as soon as possible (within 72 h or in 3 business days).
Your manuscript will be published on the web only after you approve your page proofs.
