If you are going to find information on a chemical, you have to know what to call it. Depending on where you look, you can look by--
name, but there may be multiple names for a chemical.
formula, but there may be one formula for several chemicals.
structure, but sometimes search tools will not allow you to specify stereochemistry.
mass, but more than one chemical can have the same mass.
physical properties, but there are similar physical properties for multiple chemicals.
spectra, but like a photo ID, it is difficult to search a picture.
unique identifier (i.e., the equivalent of a Social Security Number for a chemical), but you'll have to look up:
 IUPAC (International Union of Pure and Applied Chemistry) Identifier; or
 CAS (Chemical Abstracts Service) Registry Number
