  • Applications

    3-Hydroxynonanoic acid (CAS 40165-87-5) is used primarily as an industrial intermediate and building block for hydroxy-functional monomers, enabling the synthesis of polyesters and polyurethanes for plastics and coatings; it also serves as a precursor for specialty esters and bio-based polymers. Its carboxyl and hydroxyl groups permit derivatization to form surfactants and lubricant additives, and it can act as a reactive modifier in adhesive formulations. In coatings and inks, it may serve as a functional monomer or chain extender to improve film properties. Use is subject to local regulations and formulation limits.
