2-Methyl butyric acid Chemical Properties,Uses,Production
Description
2-methyl butyric acid has a pungent, acrid odor which is similar to Roquefort cheese with an acrid taste. At low dilutions, it has a pleasant fruity taste. It can be prepared either by decarboxylation of methyl ethyl malonic acid or by the oxidation of fermentation amyl alcohol (fusel oil). It is used as a flavor ingredient for butter, cream, cheese flavor deployment. It also provides acyl moiety for the preparation of the respective flavor esters.
