Description
2-Methylbutyric acid (CAS 600-07-7) is a short-chain branched carboxylic acid, also known as alpha-methylbutyric acid, active valeric acid, or FEMA 2695. It carries no assigned E-code and is classified within the C5 carboxylic acid family.
In food and beverage formulation, it functions as a flavoring agent, contributing characteristic fruity and cheesy top notes at low use levels by interacting with esterification pathways during processing. In pharmaceutical and personal care applications, its carboxylic acid group enables pH regulation and buffering, helping formulators maintain target pH ranges in complex matrices.
2-Methylbutyric acid is available in food-grade quality conforming to FCC specifications and in grades suitable for cosmetic and pharmaceutical manufacturing under REACH compliance. Procurement teams should confirm lot-specific documentation including CoA and SDS prior to ordering.
