Reaxys is the web-based successor to the Crossfire Beilstein/Gmelin system, and provides access to organic, inorganic and organometallic chemical structures, reactions, and properties contained in the Beilstein and Gmelin databases plus selective journal and patent literature.

Reaxys is a key tool for researchers who are investigating synthesis methods for chemical compounds, characterizing synthesized compounds, or searching for critically evaluated data on physical, chemical, spectral, bioactivity, or toxicological properties.
