ChemSpider

ChemSpider is a free chemical structure database providing fast text and structure search access to over 30 million structures from hundreds of data sources.

ChemSpider is a free chemical structure database providing fast text and structure search access to over 30 million structures. By integrating and linking compounds from more than 470 data sources, ChemSpider gives researchers a comprehensive view of freely available chemical data in a single online search. It is owned by the Royal Society of Chemistry.

Searches can be performed by chemical names (Systematic names; Synonyms; Trade names and Database identifiers) and chemical structure (structures may be drawn on the website or structures may be imported from a personal computer). Data include literature references, physical properties, interactive spectra and chemical suppliers.

ChemSpider can be linked to the Crystallography Open Database (COD) and vice versa.
