Propanoic acid, also known as primary oleic acid, is a short-chain saturated fatty acid with a chemical formula of CH3CH2COOH and a molecular weight of 74.08. Propanoic acid is a weak electrolyte (Ka = 1.34 × 10-5). Its aqueous solution is weakly acidic, but highly corrosive, and its vapor is irritating to the skin and respiratory tract. At room temperature and pressure, propanoic acid is a colorless, clear, oily liquid with an unpleasant, rancid, and pungent odor. It is miscible with water, ethanol, chloroform, and ether.

Propionic acid is mainly used as a food preservative and mildew inhibitor. It can also be used as an inhibitor of viscous substances in beer, a solvent and plasticizer for cellulose nitrate. It can also be used in the preparation of nickel plating solutions, food flavorings, and the manufacture of medicines, pesticides, mildew inhibitors, etc.
Propionic acid is primarily used as a food preservative and mildew inhibitor. It also serves as an inhibitor for viscous substances in beer brewing, a solvent/plasticizer for cellulose nitrate, and raw materials for medicines, food flavorings, pesticides, and nickel plating solutions.
Our Propionic Acid is of Superior Grade, featuring a minimum purity specification of 99.5%, with average test results consistently achieving 99.9%.
We maintain strict quality control standards. A pre-production sample is always evaluated prior to mass production, and a comprehensive final inspection is conducted on every batch before shipment.
