Description

2-Methylvaleric acid has a powerful, pungent, acrid odor. At concentrations below 10 ppm, it has an agreeable, sour, oily flavor. At higher concentrations the flavor becomes disagreeable because it is too acidic. clear colorless liquid

colourless to pale yellow liquid with a caramel, pungent odour

2-methylvaleric acid is a methyl-branched fatty acid that is pentanoic acid which carries a methyl group at position 2. It has a role as a flavouring agent, a plant metabolite and a fragrance. It is a branched-chain saturated fatty acid, a methyl-branched fatty acid, a monocarboxylic acid and a short-chain fatty acid. It is a conjugate acid of a 2-methylvalerate.
