Propionic Acid

Propionic acid, or propanoic acid, is a naturally occurring carboxylic acid with the chemical formula CH₃CH₂COOH. It is a colorless, oily liquid with a pungent, rancid odor. The name is derived from the Greek words "protos" (first) and "pion" (fat), as it is the smallest acid that exhibits the properties of a fatty acid. It is produced biologically by gut bacteria and is used commercially as a preservative in animal feed and human foods, particularly bread and other baked goods, to prevent mold growth. It also serves as a chemical intermediate in the production of other chemicals, including pesticides and pharmaceuticals.
