SciFinder offers: substance information including chemical structures, chemical names, CAS Registry Numbers, properties, commercial availability and regulatory information; chemical reaction information including reaction schemes, experimental procedures, conditions, yields, solvents, catalysts as well as commercial availability of substances; chemistry and related science information found in journals, patents, dissertations and more.
