General description

2-Methylbutyric acid is a short-chain fatty acid used as a chemical intermediate for plasticizers and lubricants.

Enantioselective esterification of (+/-)-2-methylbutynic acid catalyzed by Chromobacterium viscosum lipase immobilized in microemulsion-based organogels has been investigated.

Application

2-Methylbutyric acid was used in the synthesis of 2-methylbutyric anhydride, an acylating agent.
