Nonanedioic acid, also known as sebacic acid, is a dicarboxylic acid with the chemical formula C10H18O4. It consists of a straight-chain structure with two carboxylic acid groups at each end. This compound is typically found in nature, particularly in the seeds of the Jojoba plant and in certain animal fats. Nonanedioic acid is primarily used in the production of polyamides and as a plasticizer in various materials. It also serves as an intermediate in the synthesis of lubricants and surfactants. Its properties make it valuable in the manufacturing of cosmetics and personal care products as well.
