ChemRxiv (pronounced 'chem-archive') is a free submission, distribution and archive service for unpublished preprints in chemistry and related areas.

It gives researchers across a broad range of chemistry fields the opportunity to share early results with colleagues and respond to comments and recommendations for improvement, ahead of formal peer review and publication.

Use ChemRxiv to:

  • Gather feedback and context from fellow scientists
  • Rapidly disseminate work to a wide audience
  • Establish the priority and precedence of a discovery
  • Boost the visibility of research findings
  • Find potential collaborators and hold interdisciplinary discussions
  • Document research results for grant reviewers in advance of publication
  • Facilitate rapid evaluation of results
  • Spot trends and encourage a broad range of constructive feedback

All of this can improve the reliability of the final research.

Our preprints come from the author's original files, and are not prepared for publication. ChemRxiv conducts a basic screen for plagiarism, offensive language, and non-scientific content, and will exclude materials that may pose a health or security risk if identified. Beyond this, the files are unedited, and are not peer-reviewed.


If your article covers any aspect of the chemical sciences, it can be included in ChemRxiv. You will be asked to select from one of the following categories during submission:

  • Agriculture and food chemistry
  • Analytical chemistry
  • Biological and medicinal chemistry
  • Catalysis
  • Chemical education
  • Chemical engineering and industrial chemistry
  • Earth, space, and environmental chemistry
  • Energy
  • Inorganic chemistry
  • Materials science
  • Nanoscience
  • Organic chemistry
  • Organometallic chemistry
  • Physical chemistry
  • Polymer science
  • Theoretical and computational chemistry

Complementary preprint services, such as arXiv and bioRxiv, are available for articles that do not cover a relevant area of the chemical sciences.

The ChemRxiv partnership

ChemRxiv is co-owned, and collaboratively managed by the American Chemical Society (ACS), German Chemical Society (GDCh) and the Royal Society of Chemistry.

With three of the world's largest chemical societies driving its development, ChemRxiv will enable efficient and timely dissemination of chemistry knowledge, help authors and researchers around the world communicate their work across disciplines, and provide a forum through which to share and discover the very latest findings.
