  • Applications

    8-Cyclopentadecen-1-one, CAS number: 72785-16-1, is a macrocyclic ketone with a musk-like odor primarily used as a fragrance ingredient in perfumes. In perfumery, it may function as an odorant and sometimes as a fixative to extend scent longevity. It is also used in cosmetics and personal care products such as perfumes, moisturizers, and hair care items as a fragrance component. Additionally, it may appear in household products with fragrance such as air fresheners and scented cleaners. Furthermore, it can be considered an intermediate in musk-related fragrance synthesis and may be employed in coatings and inks to impart musk notes.
