Beschreibung
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.
Chemische Eigenschaften
clear colorless liquid
Chemische Eigenschaften
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
Verwenden
(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.
Verwenden
2-Methylvaleric acid is used to produce plasticizers, vinyl stabilizers, metallic salts, and alkyd resins.

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.
Allgemeine Beschreibung
2-Methylpentanoic acid is a volatile fatty acid found in tobacco and milk.
Flammability and Explosibility
Flammable
