2-Methyl butyric acid Safety Information

2-Methyl butyric acid Usage And Synthesis

Description	2-Methylbutyric acid has a pungent, acrid odor similar to Roquefort cheese with an acrid taste. At low dilutions, it has a pleasant fruity taste. May be prepared by decarboxylation of methyl ethyl malonic acid (with heat); also by oxidation of fermentation amyl alcohol (fusel oil).
