Reaxys: About Reaxys

• Reaxys can be accessed on-campus, without a username / password, as an anonymous user, although a login is required to access predictive retrosyntheses
• Use this link to go to the Reaxys Homepage
• Off campus use of Reaxys requires PennKey authentication
• Penn Libraries provides Reaxys free of charge for current Penn affiliates. 

Reaxys is now an independent database, owned and updated by Elsevier. Originally Reaxys was created as an integrated chemical information database for:

Beilstein Organic Chemistry Reactions

• From 1771 (abstracts from 1980) contains over 9.6 million organic compounds, many with property data, and over 10 million reactions. Includes pharmacology, toxicology and ecological chemistry data

Gmelin Inorganic Chemistry

• From 1700s contains over 2.4 million inorganic and organometallic compounds, 1.8 million reactions and 1.2 million references covers information about analytical chemistry, atomic physics, ores, chemical technology, electrochemistry, geochemistry, history of chemistry, colloid chemistry, coordination chemistry, corrosion and passivity, crystallography, geology, metallography, metallurgy, mineralogy, non-ferrous metals, physical properties (crystallographic, mechanical, optical, magnetic, electrical), toxicity and hazards, economic and statistical data.

Patent Chemistry

• Selected organic chemistry patent publications (1869 -1980) US, World and European patents from 1976 for Patent classes: Organic Chemistry, Medicinal Preparations, Biocides, Agrochemicals and Dyes

Reaxys still contains the information from the original databases, however any new information is added from Elsevier. Beilstein and Gmelin still exist but are no longer adding information to Reaxys.
