Valeric acid
Valeric acid, or pentanoic acid, is a straight-chain alkyl carboxylic acid with the chemical formula. Like other low-molecular-weight carboxylic acids, it has an unpleasant odor. It is found in the perennial flowering plant valerian, from which it gets its name. Its primary use is in the synthesis of its esters. Salts and esters of valeric acid are known as valerates or pentanoates. Volatile esters of valeric acid tend to have pleasant odors and are used in perfumes and cosmetics. Ethyl valerate and pentyl valerate are used as food additives because of their fruity flavors.Production
It is produced industrially by the oxidation of valeraldehyde. It can be produced from biomass-derived sugars via levulinic acid.
Valeric acid is one volatile component in swine manure. Other components include other carboxylic acids, skatole, trimethyl amine, and isovaleric acid.Safety
Valeric acid can cause irritation if it comes into contact with the skin, eyes, or mucous membranes.
