| Hazard Information | Back Directory | [Description]
2-Methylheptanoic acid has a fatty, sour odor (rancid-like) with a
sour, fruity, and nut-like flavor. May be synthesized by decarboxylation of methylamyl malonic acid; two optically active isomers
and an optically inactive form can be prepared. | [Chemical Properties]
