How to Cite Journal Articles in ACS Style

ACS Journal Article Citation Basics

Journal articles are among the most frequently cited sources in chemistry and chemical research. ACS provides a standardized format that ensures consistency and clarity while accommodating the distinctive needs of chemical literature. Understanding the correct structure is essential for maintaining academic integrity in chemistry publications.

The ACS format for journal articles emphasizes essential information while providing sufficient detail to locate and verify sources. This precision is particularly important in chemistry where experimental details and reaction conditions often require verification by other researchers.

Complete Journal Article Format

The standard ACS format for journal articles is:

Number. Author(s); Journal Abbreviation Year, Volume, page. DOI

Example with all elements:

1. Martinez, J. L.; Rodriguez, C. P.; Thompson, M. K. Efficacy of Novel Catalytic Methods in Organic Synthesis. J. Org. Chem. 2025, 90, 234–245. DOI: 10.1234/joc.2025.001

Breaking down this example:

• 1. = Reference number
• Martinez, J. L.; Rodriguez, C. P.; Thompson, M. K. = Authors (all listed, separated by semicolons)
• Efficacy of Novel Catalytic Methods in Organic Synthesis = Article title
• J. Org. Chem. = Journal abbreviation (italicized)
• 2025 = Publication year (bold)
• 90 = Volume (bold)
• 234–245 = Page range (with en-dash)
• DOI: 10.1234/joc.2025.001 = Digital Object Identifier

Author Name Formatting

List authors exactly as published, with initials and surnames:

Martinez, J. L.; Rodriguez, C. P.; Thompson, M. K.

All authors are typically listed in ACS format. Use semicolons (not commas) to separate authors, and follow initials with periods.

Article Title Formatting

The article title appears in regular font with standard capitalization. Unlike some styles, ACS does not use quotation marks around article titles:

Efficacy of Novel Catalytic Methods in Organic Synthesis

Capitalize the first word and proper nouns, but use lowercase for other words (sentence case):

Synthesis of novel heterocyclic compounds using microwave-assisted methods

Journal Title Abbreviations

Journal titles must be abbreviated according to Chemical Abstracts Service (CAS) standards. This is crucial for ACS compliance. Common abbreviations:

• Journal of Organic Chemistry → J. Org. Chem.
• Journal of the American Chemical Society → J. Am. Chem. Soc.
• Angewandte Chemie International Edition → Angew. Chem., Int. Ed.
• Tetrahedron Letters → Tetrahedron Lett.
• Chemical Reviews → Chem. Rev.
• Analytical Chemistry → Anal. Chem.
• Journal of Medicinal Chemistry → J. Med. Chem.
• Inorganic Chemistry → Inorg. Chem.

Verify abbreviations in the Chemical Abstracts Service Source Index to ensure accuracy.

Year and Volume Formatting

Both year and volume appear in bold (when formatting allows):

J. Org. Chem. 2025, 90, 234–245

The year is bold, followed by a comma, then the bold volume number.

Page Number Conventions

Always include the complete page range:

234–245

Use an en-dash (–) rather than a hyphen (-) to separate page numbers. This is a distinctive feature of ACS formatting.

DOI Inclusion and Formatting

Include DOI when available:

DOI: 10.1234/joc.2025.001

Or as a URL:

https://doi.org/10.1234/joc.2025.001

Some ACS publications include DOI at the end; others integrate it into the citation. Check your target publication’s specific format.

Electronic Journal Articles

For online-only journals or articles with electronic publication dates:

2. Anderson, K. L.; Peterson, R. J. Remote Patient Monitoring in Clinical Chemistry. J. Clin. Chem. 2026, 162, article e124504. DOI: 10.1234/jcc.2026.001

Note the “article” designation when traditional page numbers aren’t available.

Ahead-of-Print Articles

For articles published ahead of print (before volume/issue assignment):

3. Chen, M. L.; Walsh, S. J. Immunochemical Techniques in Molecular Biology. J. Biol. Chem. 2026, e20250456. DOI: 10.1234/jbc.2026.e20250456

Include the article number instead of page numbers.

Supplementary Materials

When citing supplementary materials published with an article:

4. Johnson, T. A.; Williams, B. C. Synthetic Procedures and Spectroscopic Data. J. Org. Chem. 2025, 90, 456–467. DOI: 10.1234/joc.2025.004

Supporting Information available at: https://doi.org/10.1234/joc.2025.004.si

Chemical Compound Information

Include relevant chemical information that enhances the citation:

5. Thompson, J. R.; Anderson, M. L. Synthesis of Benzofuran Derivatives via Palladium-Catalyzed Cyclization. J. Org. Chem. 2025, 90, 678–689. DOI: 10.1234/joc.2025.005

The article title already indicates specific compounds studied.

Retracted Articles

If citing a retracted article, note the retraction:

6. Smith, J. A.; Rodriguez, M. C. Initial Findings on Experimental Treatment. J. Chem. Phys. 2024, 160, 234–242. Retracted in: J. Chem. Phys. 2025, 162, XXX.

Using GenText for Journal Article Citations

GenText streamlines journal article citation formatting by automatically organizing author information with proper semicolons, correctly abbreviating journal titles from CAS standards, formatting year and volume in bold, and structuring all elements according to ACS specifications. The platform saves time and ensures accuracy in complex citations.

Common Errors in Journal Citations

Error 1: Using full journal names instead of abbreviations Incorrect: Journal of Organic Chemistry Correct: J. Org. Chem.

Error 2: Using hyphens instead of en-dashes for page ranges Incorrect: 234-245 Correct: 234–245

Error 3: Inconsistent author formatting or using commas instead of semicolons

Error 4: Omitting issue numbers when the journal is paginated by issue (typically acceptable to omit in ACS)

Special Citation Circumstances

Multiple Articles by Same Author, Same Year: Distinguish with letters if necessary:

7a. Thompson, J. R.; Anderson, M. L. First Article Title. J. Org. Chem. 2025, 90, 100–110. DOI: 10.1234/joc.2025.001

7b. Thompson, J. R.; Anderson, M. L. Second Article Title. J. Org. Chem. 2025, 90, 200–210. DOI: 10.1234/joc.2025.002

Articles with Organizational Authors: When an institution is listed as author:

8. National Institute of Standards and Technology. Chemical Database Properties. J. Phys. Chem. Ref. Data 2025, 54, 023101. DOI: 10.1234/jpcrd.2025.023101

Early Online Publication: For articles available online before print publication:

9. Williams, D. D.; Martinez, S. J. Novel Catalytic Approaches. J. Am. Chem. Soc. 2025, 147, e12345. DOI: 10.1234/jacs.2025.e12345

Verification Checklist

Before finalizing your citations:

• Verify all author names and surnames
• Confirm journal abbreviation matches CAS standards
• Check volume number and year
• Verify complete page range with en-dashes
• Include DOI if available
• Ensure title capitalization follows ACS conventions
• Confirm punctuation between elements
• Verify formatting (bold for year/volume when applicable)

Hierarchical Citation Ordering

When citing multiple articles for the same proposition, order them appropriately based on publication date or relevance:

1. Smith, J. A.; Johnson, B. C. Early Study. J. Org. Chem. 2020, 85, 100–110. DOI: 10.1234/joc.2020.001

2. Williams, D. D.; Martinez, S. J. Recent Advancement. J. Org. Chem. 2025, 90, 234–245. DOI: 10.1234/joc.2025.001

Conclusion

Properly citing journal articles in ACS style demonstrates mastery of chemical citation conventions and ensures your work meets professional publication standards. By understanding the format structure, using correct journal abbreviations, and maintaining consistency in formatting, you provide readers with precise access to chemical literature. Combined with tools like GenText, which manage technical details automatically, you can focus on the substance of your chemical research while maintaining citations that reflect scientific excellence and integrity.
