2-METHYLVALERIC ACID Usage And Synthesis

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