The Beilstein database contains information on substances, including coverage of reactions, structures and properties. Up to 350 fields containing chemical and physical data (such as melting point, refractive index, and so on) are available for each substance. References to the literature in which substance data appears are also given.
The Beilstein data is made available in the CrossFire Beilstein database by Elsevier MDL, a subsidiary of Elsevier. CrossFire also offers access to Gmelin, a very large database of organometallic and inorganic chemical information, through CrossFire Gmelin, and the Organic Chemistry from Chemistry Patents through the MDL Patent Chemistry Database.
CrossFire Databases are available through MDL's native interface, CrossFire Commander in its latest Version 7.0 SP2, or through DiscoveryGate.
