  • Applications

    2-Aminopropanol (CAS number: 6168-72-5) is used as a chemical intermediate in the production of polyurethane foams and elastomers, where it reacts with diisocyanates to form urethane linkages; it also serves as a building block for surfactants and polymeric surfactants used in cleaners, coatings, and cosmetic formulations; it can function as a reactive solvent and processing aid in coatings, inks, and adhesive resins; and it is employed as an intermediate in the synthesis of pharmaceutical and agrochemical active ingredients or intermediates.
