  • Applications

    3-Hexanone (CAS 589-38-8) is used as an organic solvent in industrial manufacturing, serving as a processing solvent for coatings, inks, and adhesives. It also functions as a chemical intermediate in organic synthesis, enabling the production of fragrance compounds and other fine chemicals. In perfumery and cosmetics, it may be used as a solvent or odorant component in fragrance formulations. It is employed in cleaning formulations as a solvent and can act as a processing solvent or carrier in polymer/plastics applications. Its role as a versatile solvent and intermediate is commonly exercised under appropriate formulation limits and regulatory requirements.
