CAS 116-53-0: 2-Methylbutanoic acid

Description:2-Methylbutanoic acid, also known as isovaleric acid, is a branched-chain carboxylic acid characterized by its five-carbon backbone with a methyl group attached to the second carbon. It has the molecular formula C5H10O2 and features a carboxyl functional group (-COOH), which imparts acidic properties. This compound is typically a colorless liquid with a pungent odor reminiscent of cheese or sweaty feet, often associated with its presence in certain fermentation processes. 2-Methylbutanoic acid is soluble in water and organic solvents, making it versatile in various applications. It is used in the synthesis of esters for flavoring and fragrance industries, as well as in the production of pharmaceuticals and agrochemicals. Additionally, it can be found in some natural sources, including certain essential oils and as a byproduct of microbial metabolism. Its reactivity includes typical carboxylic acid behavior, such as undergoing esterification and participating in various organic reactions. Safety precautions are necessary when handling this substance due to its strong odor and potential irritant properties.
