  • Applications

    2-Cyclopentadecenone (CAS 89308-00-9) is an unsaturated macrocyclic ketone used primarily as a musk ingredient in perfumery, delivering a warm, soft, clean, slightly animalic/amber tonal profile with strong substantivity; it serves both as a character note and as a fixative to enhance longevity, diffusion, and accord cohesion, bridging floral, woody, and amber facets; applicable to fine fragrances, personal care, and home care fragrances (e.g., fabric conditioners, scented cleaners), including encapsulated and controlled-release systems; in R&D it is employed for structure–odor relationship studies, as a GC/MS reference and for fragrance quality control; synthetically, its double bond and carbonyl enable hydrogenation (to cyclopentadecanone/exaltone-type materials), epoxidation, and Michael additions to build libraries of macrocyclic musks and functionalized analogs; it is often selected as a vegan alternative to animal-derived musk nuances and is used within relevant safety/IFRA guidance depending on end-use.
