  • Applications

    Muquketone (CAS 55638-41-0) is primarily used as an intermediate in organic synthesis and is also evaluated as a solvent or processing aid in various industrial applications. In perfumery and cosmetics, it may function as an odorant precursor or fragrance component, contributing to scent profiles. In coatings, inks and adhesives, it can serve as a chemical intermediate or solvent to aid formulation and processing. In polymers and plastics, it is considered as a potential monomer precursor or processing additive for specialty materials. In household and cleaning products, it may appear as a solvent or formulation aid, subject to regulatory and formulation limits.
