Great databases for chemical and physical properties of all compounds.
CRC handbook of Chemistry and Physics is an easier source to use
for physical properties of more common compounds. These databases
are best searched by chemical structure.
Beilstein covers organic compounds
Gmelin covers organometallic & inorganic compounds.
Beilstein is useful for chemical and physical properties, synthesis
and chemical reactions of over 8 million organic compounds. The
Gmelin database covers more than 1.4 million organometallic and
inorganic compounds (including coordination compounds, alloys, glasses,
ceramics, polymers and minerals), with more than 800 property fields
