Reaxys provides web-based access to chemical structure, reaction and property information; its contents are derived from Beilstein (organic compounds) and Gmelin (inorganic and organometallic compounds), which date to the 18th and 19th centuries, as well as selected English-language chemical patents (US,EP, and WO) from 1976-present).
NOTE: Reaxys is moving to a new platform and we will be updating our links to this resource prior to the end of May.
