Government agencies have lots of great information related to chemical substances, especially practical aspects & current issues.

Limit by domain name to see results only from .gov sites.  Example: vitamin C

The American Chemical Society's Chemical Abstract Service (CAS) has assigned a unique number to more than 133 million chemical substances.
