  • Applications

    Oct-5-EN-2-one (CAS 36359-70-3) is used primarily as a fragrance ingredient and odorant, serving as a building block for perfumery notes and related aroma formulations. It is often evaluated as an aromatic intermediate for cosmetic and personal-care products, and may appear in household products as a scent additive or minor fixative. In industrial manufacturing, it can function as a fragrance-related intermediate for chemical syntheses. It is also applicable in coatings and inks as an odorant additive and in cleaning products to provide controlled fragrance profiles.
