The Beilstein database is one of the largest databases in the field of organic chemistry, in which compounds are uniquely identified by their Beilstein Registry Number. The database covers the scientific literature from 1771 to the present and contains experimentally validated information on millions of chemical reactions and substances from original scientific publications. The electronic database was created based on Beilstein's Handbook of Organic Chemistry, founded by Friedrich Konrad Beilstein in 1881, and is maintained by Elsevier Information Systems in Frankfurt.
The Beilstein database contains information on reactions, substances, structures and properties. Up to 350 fields containing chemical and physical data (such as melting point, refractive index etc.) are available for each substance. References to the literature in which the reaction or substance data appear are also given.
The content is made available through the "CrossFire Beilstein" database. Information is complemented by "CrossFire Gmelin" which gives access to the Gmelin Database, a very large repository of organometallic and inorganic information (owned by the German Chemical Society (Gesellschaft Deutscher Chemiker)) and organic chemistry from chemistry patents through the Patent Chemistry Database.
The Beilstein Database is also available through Dialog and STN International's interface.
Since January 2009 the information of the three mentioned databases has also been available through a new online tool called "Reaxys". The contents of the three databases have been merged and are accessible through a new interface and new functionalities which help to e.g. plan a chemical synthesis.
