  • Applications

    Karahana ether (CAS 19901-96-3) is used as a specialty solvent and reaction medium in various industrial formulations. In coatings and inks, it acts as a co-solvent and processing aid to improve dissolution of resins and pigments. In polymer and plastics processing, it serves as a processing solvent or plasticizer where compatible with the matrix. It is sometimes employed as an intermediate in organic synthesis for niche chemicals, and in perfumery and cosmetics as a solvent or odorant carrier within controlled formulations. It can also be used in household products and cleaning formulations as a solvent for actives. Its use is subject to local regulations and formulation limits.
