Valeric acid or pentanoic acid is a straight-chain alkyl carboxylic acid with the chemical formula CH
3COOH. Like other low-molecular-weight carboxylic acids, it has an unpleasant odor. It is found in the perennial flowering plant valerian (Valeriana officinalis), 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.
Valeric acid can cause irritation if it comes into contact with the skin, eyes, or mucous membranes.
