Reaxys is a web-based tool with a java structure editor for searching the Beilstein/Gmelin database and a Patent database. Reaxys is replacing Beilstein Crossfire Commander as the Beilstein/Gmelin access tool.

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

Reaxys merges the content from three major data sources:

  • Beilstein: a critically reviewed and evaluated source of information on the structures, reactions, and properties of organic carbon compounds, drawn from the journal literature back to the 18th century. 
  • Gmelin: a critically reviewed and evaluated source of information on structures and properties of inorganic and metal-organic compounds, drawn from the journal and patent literature back to the early 19th century. 
  • Patent Chemistry Database: a file of organic chemistry information drawn from selected English-language chemical patents (US, WO, EP, 1976- ). Additional historical (1869-1980) patent coverage comes from the Beilstein and Gmelin files.
