Description and Uses
Pyrrolidine is a flammable alkaline liquid that undergoes reactions typical of secondary amines. It is used to prepare pesticides and rubber accelerators and as a chemical intermediate (usually the hydrochloride form) in the pharmaceutical industry. There is relatively limited industrial exposure to this material.
