Reaxys (1771+) is a database of chemical compound properties, structures, and reactions with references to the journal and patent literature of chemistry. The data originates from the Gmelin Handbook of Inorganic Chemistry, the Beilstein Handbuch der Organischen Chemie, inorganic and organic chemistry journals and a Patent Chemistry database. Flexible and powerful substance searching includes exact structure, substructure, CAS number, molecular formula, name, and many more choices.  Can also search by property and/or reaction.


Reaxys is available on internet at https://www.reaxys.com or via Reaxys on the Find Databases page. Access is restricted to University of Rochester students, faculty, and staff.   Contact Chemistry Librarian Sue Cardinal (contact info above) for assistance with searching.

Reaxys In Detail

Reaxys provides excellent coverage of property information for chemical compounds. Can search by many different properties and subject terms.  Substructure and reaction searching is flexible and comprehensive. When searching reactions, you can specify the product and/or one or more reactants. Because of the indexing policy, reaction searching has been more comprehensive than SciFinder for journal articles. You can search by name fragments. CAS numbers may be searched, however, they were no longer added after ~1995.   Reaxys is especially useful for finding articles about biological activity of substances.  Subject searching has improved with the addition of some new content.


Reaxys contains information about coordination compounds, alloys, solid solutions, glasses, ceramics, minerals, catalysts and polymers. The Gmelin side of this database includes compounds that contain no carbon, and "inorganic" systems with a carbon component (carbides, carbonic acid, CO, CO2, etc.) and elemental carbon and elements listed below including their coordination and organometallic compounds.
