Description

9-Cycloheptadecen-1-One is a high-purity macrocyclic ketone, a key building block in the synthesis of complex fragrance and flavor compounds. Its unique 17-membered ring structure with an internal double bond provides a distinct musky-woody olfactory profile, making it invaluable for creating sophisticated and long-lasting scent accords. This intermediate is essential for manufacturers in the fine fragrance, personal care, and specialty chemical industries seeking to develop premium, high-performance aroma molecules.

Application

• Fragrance & Flavor Intermediate: A crucial precursor in the synthesis of high-value macrocyclic musks and other specialty aroma chemicals.
• Fine Fragrance Formulation: Used to impart or enhance musky, woody, and amber notes in premium perfumes, eau de toilettes, and colognes.
• Personal Care Products: Incorporated into the production of scented soaps, lotions, deodorants, and hair care products for long-lasting fragrance.
• Functional Perfumery: Serves as a base note and fixative in air fresheners, fabric softeners, and household cleaning products.
• Chemical Research & Development: A valuable intermediate for organic chemists exploring novel macrocyclic compounds and ring-expansion reactions.
• Specialty Polymer Additives: Investigated for use in modifying polymer properties or as a monomer for specific polyketone syntheses.
