Reaxys is a web-based tool for the retrieval of information about chemical compounds and data from published literature, including journals and patents.
It was developed to provide research chemists with access to current and historical, relevant, organic, inorganic and organometallic chemistry information, from reliable sources via an easy-to-use interface.
[2] One of the primary goals of Reaxys is to provide research chemists with access to experimentally measured data – reactions, physical, chemical or pharmacological – in one universal and factual platform.
[3] Content covers organic, medicinal, synthetic, agro, fine, catalyst, inorganic and process chemistry and provides information on structures, reactions, and citations.
PubChem should also be included, not only because of its size and accessibility... Reaxys has well over 100 times the number of experimental property data points
