  • Applications

    Pinguisone (CAS 22489-40-3) is used primarily as an aromatic ingredient and as an intermediate in chemical synthesis across multiple sectors. In perfumery and cosmetics, it may serve as a fragrance component or odorant, while in household products it can be evaluated as a scent additive or conditioning agent. In industrial manufacturing it is often used as a solvent or processing aid for specialty formulations, and it may act as a stabilizer or plasticizer in polymers or coatings depending on its compatibility. It is also considered for use in coatings, inks, and adhesives as a functional additive, subject to local regulations and formulation limits.
