(S)-4-(2-Methylpropyl)-2-pyrrolidinone

Controlled Product

CAS: 181289-23-6

(S)-4-(2-Methylpropyl)-2-pyrrolidinone is a lactam that has been synthesized in the laboratory. It is an organic solvent that is used in the synthesis of other compounds. The compound has a potential for producing impurities, such as isopropyl and phosphite, during synthesis. (S)-4-(2-Methylpropyl)-2-pyrrolidinone can be synthesized by reacting 2-methylpropionic acid with one equivalent of methylamine. This reaction takes place in an organic solvent and requires kinetic control to avoid side reactions.
