2-METHYLVALERIC ACID

Description

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.

Chemical properties

clear colorless liquid

Chemical properties

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.

Occurrence

Reported found in coffee, wine, cheese, papaya, baked potato, pepper, lamb, rum, tea, mango and cherimoya

The Uses of 2-METHYLVALERIC ACID

2-Methylvaleric acid is used to produce plasticizers, vinyl stabilizers, metallic salts, and alkyd resins.

The Uses of 2-METHYLVALERIC ACID

(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.

Preparation

Definition

ChEBI: 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.

General Description

2-Methylpentanoic acid is a volatile fatty acid found in tobacco and milk.
