  • Applications

    Fusalanipyrone (CAS 118169-29-2) is typically encountered as an intermediate in organic synthesis and may be evaluated for use in fragrance chemistry as an odorant or precursor to heterocyclic aroma compounds; it can also function as a solvent or processing additive in specialty coatings and inks, and may serve as a stabilizer or chelating agent in certain industrial formulations, with potential applications in polymers/plastics and cleaning products, all subject to local regulations and formulation limits.
