Undecanoic Acid (C11:0), also known as undecylic acid, is a saturated fatty acid composed of an 11-carbon atom chain. Known for its antifungal, antimicrobial, and surface-active properties, it finds widespread applications across pharmaceutical, cosmetic, plastics, and metalworking industries. At Acme Synthetic Solutions, we manufacture and supply high-purity Undecanoic Acid from natural and sustainable feedstocks, offering consistent quality and customized supply solutions for global customers.
Undecanoic Acid is a medium-chain saturated fatty acid derived primarily from castor oil or ricinoleic acid via pyrolysis. It presents as a white crystalline solid or oily substance, depending on temperature, and is insoluble in water but soluble in most organic solvents.
