  • Applications

    Hexadecylamine (CAS 143-27-1) is a long-chain primary fatty amine used as an intermediate and building block in chemical manufacturing. It is commonly used to synthesize cationic surfactants and quaternary ammonium compounds for detergents, cleaners, textiles, and personal-care products. It serves as a raw material or reactive component in epoxy and polyurethane systems, where it can act as a curing agent or reactive diluent. It also functions as a surfactant and emulsifier in agrochemical formulations and metalworking fluids, aiding emulsion stability and providing lubricity and corrosion inhibition. Additionally, it may be used as a precursor to fragrance-related intermediates in perfumery and other specialty chemicals, subject to formulation requirements and regulations.
