Reaxys is a web-based interface for three chemical information databases: CrossFire Beilstein, CrossFire Gmelin, and Patent Chemistry Database (PCD) . It allows searching by

• Substances: fully searchable chemical structures. Substance records show physical, chemical and bioactivity data – including pharmacodynamics and (eco-)toxicology data from different publications.
• Reactions: fully searchable single and multi-step reactions, many with reaction procedure texts.
• Citations: indexed from the primary organic, inorganic and organomatellic chemistry journal literature going back to 1772 and patent literature.
