Application
Isononanoic acid (CAS 26896-18-4) is a branched-chain C9 carboxylic acid with excellent thermal and oxidative stability. It is primarily used as a key intermediate for the synthesis of synthetic ester lubricants, including polyol esters and neopentyl glycol esters, which serve as high-performance base oils for refrigeration compressors, jet engines, and industrial hydraulics. It also produces isononyl alcohol and isononyl esters used as PVC plasticizers (e.g., DINP), providing superior flexibility and low-temperature performance. In the metalworking industry, its derivatives act as corrosion inhibitors and emulsifiers. Additionally, isononanoic acid finds applications as a paint drier, stabilizer for PVC heat stabilizers, and in the production of alkyd resins, cosmetics, and personal care emollients.
