  • Applications

    m-Cymene (CAS 535-77-3) is an aromatic hydrocarbon primarily used as a component in fragrance and perfumery, while also serving as a solvent for coatings, paints, inks, and industrial cleaners; it is also employed as a precursor or intermediate in the synthesis of aromatic and specialty chemicals; additionally, it can function as a feedstock in polymer/plastics manufacturing through chemical modification.
