  • Applications

    9-Hydroxydecanoic acid (CAS 1422-27-1) is a fatty acid with a hydroxyl group at C9 and is used as a functional building block and intermediate in various industrial formulations: it can be used as a starting material for the synthesis of ester derivatives and as a polyol precursor for bio-based polyurethanes and polyesters; it can serve as a platform for ester-based plasticizers and lubricant additives for polymer and coating systems; it can act as a precursor for surfactant-related esters and other specialty additives used in coatings and inks; and it is being explored as a platform for biobased polymers and specialty polymers.
