Description and Uses

Isovaleric acid has a characteristic disagreeable odor. It is extremely penetrating and persistent with a sour taste. May be synthesized by oxidation of isoamyl alcohol or isovaleric aldehyde.

Isovaleric acid is used extensively as a flavoring ingredient in nonalcoholic beverages and in foods such as ice cream, candy, baked goods, and cheese, as a fragrance ingredient in perfumes, and as a chemical intermediate in the manufacture of sedatives and other pharmaceutical products. It is also used as an extractant of mercaptans from petroleum hydrocarbons, a vinyl stabilizer, and as an intermediate in the manufacture of plasticizers and synthetic lubricants.
