Chemistry

Includes the CRC Handbook of Chemistry and Physics and several "dictionaries" that are more like handbooks.

Comprehensive database for chemistry, biochemistry, materials science, and related subjects. It includes information on substances, reactions, and provides structure and substructure searching. Indexes journals, patents, conference proceedings, and some technical reports. Coverage 1907-present.

Contains the Beilstein (organic) and Gmelin (inorganic) handbooks, which provide extensive amount of physical property data and synthesis information. Also includes chemical patents. Can be searched by CAS, formula, structure, reaction, as well as by various other parameters.

PubChem is the world's largest collection of freely accessible chemical information. Search chemicals by name, molecular formula, structure, and other identifiers. Find chemical and physical properties, biological activities, safety and toxicity information, patents, literature citations and more.

This multidisciplinary citation database indexes over 7,000 science journals, as well as conference proceedings. Coverage 1900-present.
