  • Applications

    1-Ethyl-4-methoxybenzene (CAS 1515-95-3) is mainly used as an odorant in perfumery and cosmetics; it also serves as an intermediate or building block in the synthesis of aroma and flavor compounds for the fragrance and flavor industries. It may be used as a note in cosmetics and personal care products to impart a fragrance, and may be added to household products such as cleaners, laundry products, and air fresheners to provide a scent. In industrial manufacturing, it serves as an intermediate for the synthesis of related aromatic fragrance compounds; in coatings/inks and polymer applications, it can be used as a precursor for fragrance-related chemicals used to introduce or modify aroma in resin systems, coatings, and adhesives.
