Sebacic acid is widely used to produce a salt derivative, the (di)sodium sebacate, which is a corrosion inhibitor. The main application of this salt is coolant (anti-freeze) fluids for aircraft, automotive and truck engines.
Sebacic acid is produced from castor oil by cleavage of ricinoleic acid, which is obtained from castor oil. Octanol is a byproduct.
Sebacic acid is used as a monomer for nylon 610, plasticizers, lubricants, hydraulic fluids, cosmetics and candles. It is also used as intermediates in antiseptics, aromatics and painting materials. It is used in the synthesis of poly(glycerol sebacate) and novel bio-nylon.
