    Direct answer: ACS citation generator

    An ACS citation generator formats chemistry references in American Chemical Society style. This page also works as an ACS reference generator, ACS citation maker, and ACS format generator for journal articles, DOI sources, websites, patents, books, preprints, in-text citations, and reference lists. The key ACS citation format usually keeps authors, title, source, year, volume, pages, patent details, and DOI in a consistent chemistry-focused order.

    How to use the ACS citation generator

    Choose a source type, paste a DOI, URL, patent number, or title, then fill in the citation fields. Select superscript numbers, italic numbers in parentheses, or author-date style before copying your reference.

    How to make an ACS citation

    1. Choose the source type: journal article, DOI source, patent, website, book, preprint, or dataset.
    2. Paste a DOI, URL, patent number, PMID, or title when available, then complete the source fields.
    3. Review the journal abbreviation, year, volume, pages, DOI URL, access date, or patent details required by that source type.
    4. Generate the reference, copy the matching in-text citation, or add the entry to the reference list before export.

    Core ACS citation tool entries

    ACS citation maker for American Chemical Society references

    This page is intended for searches such as ACS citation generator, ACS reference generator, ACS citation maker, ACS format generator, and American Chemical Society citation. Start with the main form, then move to the DOI, journal article, patent, in-text citation, and reference-list pages when you need a source-specific check.

    ACS format citation generator

    Use this ACS format citation generator when you need reference-list entries that follow common ACS patterns for journal articles, patents, books, websites, preprints, and DOI-based chemistry sources.

    ACS style citation generator for chemistry papers

    This chemistry citation generator is built around ACS style citation details such as journal abbreviations, numbered in-text citations, DOI links, patent numbers, access dates, and source-specific reference templates.

    ACS in-text citation vs reference list

    An ACS in-text citation is the short marker inside the paper, such as a superscript number, italic number in parentheses, or author-date citation. An ACS reference list entry is the full source record at the end of the paper. Use the in-text citation generator to place the marker, then use the ACS reference generator to build the complete journal article, DOI, patent, book, or website entry.

    ACS citation checklist

    • Choose the exact source type before entering details.
    • Use journal abbreviations when your instructor or journal expects ACS journal style.
    • Include DOI URLs for journal articles, datasets, and preprints when available.
    • For patents, include inventors, patent number, assignee, country or patent office, and publication date.
    • Keep one in-text citation style throughout the paper.

    ACS journal article citation format

    ACS journal article citations should include authors, article title, journal abbreviation, year, volume, issue when needed, pages, and DOI.

    ACS patent citation format

    ACS patent references are a core chemistry use case. Include inventors, patent title, country or patent office, patent number, assignee, publication date, and URL when available.

    ACS website citation format

    ACS website citations identify the organization or author, page title, website name, URL, and access date.

    ACS book citation format

    ACS book citations commonly include authors or editors, title, edition, publisher, place, year, and pages when citing a specific section.

    DOI lookup and Crossref metadata

    When you paste a DOI, the tool checks Crossref for public metadata and fills available article fields. Always review imported metadata before submission because DOI records can omit issue numbers, use title casing that needs adjustment, or list online-first publication details.

    ACS in-text citation styles

    ACS supports three in-text citation modes: superscript numbers, italic numbers in parentheses, and author-date. Use the option required by your instructor, department, or target journal.

    ACS reference list examples

    The generator stores references locally in your browser. Add each citation to the list, then export RTF, TXT, BibTeX, or RIS when your draft is ready.

    How this tool is reviewed

    Chem Citation Tools maintains this page as an independent educational utility. The examples are reviewed against public ACS citation patterns and refreshed when tool behavior, source fields, or cited style guidance changes.

    Common ACS citation mistakes

    • Treating ACS like APA and skipping journal abbreviations.
    • Using a generic citation format for patents.
    • Leaving DOI and access-date details out of web or dataset sources.
    • Switching between numbered and author-date in-text styles in the same paper.
