| Hazard Information | Back Directory | [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]
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. | [Chemical Properties]
clear colorless liquid | [Occurrence]
Reported found in coffee, wine, cheese, papaya, baked potato, pepper, lamb, rum, tea, mango and cherimoya | [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. | [Preparation]
By catalytic oxidation of 2-methyl pentanealdehyde; from 2-chloropentane with sodium and CO2 under pressure; by
decarboxylation of methyl propyl malonic acid; two optically active isomers are known | [General Description]
2-Methylpentanoic acid is a volatile fatty acid found in tobacco and milk. | [Flammability and Explosibility]
Flammable |
