Description and Uses

2-Methylvaleric acid has a powerful, pungent, acrid odor. Below 10 ppm the flavor is agreeable, sour, and oily. At higher concentrations, the flavor is too acidic. May be prepared by catalytic oxidation of 2-methyl pentanealdehyde; from 2-chloropentane with sodium and C02 under pressure; by decarboxylation of methyl propyl malonic acid; two optically active iosmers are known.

(R,S)-2-methylvaleric acid is an intermediate in the synthesis of branched-chain. 2-Methylpentanoic acid (2-Methylvaleric acid) was used as an internal standard for gas chromatographic analysis of microbial end products.
