  • Applications

    p-Isopropylphenetole (CAS 4132-79-0) is an aromatic ether used as an intermediate and fragrance-related ingredient in several industries. In perfumery and cosmetics, it functions as a fragrance component or odorant; in household products and cleaning formulations it may serve as a scent additive and solvent for other active ingredients. It is also evaluated as an intermediate in industrial manufacturing and organic synthesis, enabling the preparation of more complex aroma compounds or other intermediates. In addition, its aromatic structure can make it relevant in certain coatings, inks, or plastics-related formulations as a fragrance or processing aid, subject to formulation limits and local regulations.
