ChemSpider is a chemistry search engine built with the intention of aggregating and indexing chemical structures and their associated information into a single searchable repository and making it available to everybody, at no charge. ChemSpider is a value-added offering since many properties have been added to each of the chemical structures within the database – structure identifiers such as SMILES, InChI, IUPAC and Index Names as well as many physicochemical properties.
Free chemical structure search engine. Millions of public domain structures. Very fast substructure searching. Results link to data about these structures.
Chemical Information Resources pointing to biomedical information, ChemIDplus structure/name file, HSDB structure file, NCI3D Structure file, search by name, struucture, substructure with hyperlinked locators for immediate searches of toxic...
