Overview

Reaxys is a professional chemistry research platform that gives scientists access to deeply curated data on chemical reactions, substances, and experimental properties. It’s widely used in academic labs, pharmaceutical R&D, and industrial chemistry teams.

Chemistry research lives and dies on data quality. Reaxys matters because it pulls together trusted experimental data from journals and patents into one searchable system. Instead of digging through PDFs, you can quickly answer questions like “Has this reaction been done before?”, “Under what conditions?”, and “What yields were reported?”. It’s especially valuable for synthetic chemists, medicinal chemists, and process development teams where mistakes are expensive.

Reaxys indexes millions of reactions and compounds extracted and curated from peer-reviewed literature and global patent sources. You search by structure, substructure, reaction scheme, name, or property. Results show experimental conditions, yields, solvents, catalysts, and linked references.

FAQ

Can I use Reaxys data for commercial research?
Yes. Reaxys is widely used in commercial R&D environments. You can use the insights internally, but you can’t redistribute the data itself.
Is Reaxys suitable for students?
Yes, but usually through a university license. Many chemistry programs provide campus-wide access.
Does Reaxys include patents?
Yes. A major strength of Reaxys is its deep coverage of global patent chemistry alongside journal literature.
Can I draw chemical structures to search?
Yes. Reaxys supports structure and substructure searches using built-in drawing tools.
Does Reaxys replace lab experimentation?
No. It reduces guesswork and duplication, but experimental validation is still required.
Is there an API for automation?
Public API access is not clearly documented. Most users access Reaxys through the web interface.
