2-Hexylidenecyclopentan-1-one (CAS 17373-89-6) is commonly used in perfumery as a fragrance ingredient and as an intermediate in the synthesis of other aroma compounds; it may be added to cosmetics and personal care products to impart a woody-green note, and to household cleaning products and air fresheners for scent release. In industrial manufacturing, it serves as a building block in fragrance libraries and may be used as an odorant additive in coatings, inks, and other consumer and industrial formulations, all subject to local regulations and formulation limits.
