  • Applications

    alpha-Amyrenone (CAS 638-96-0) is primarily used as an odorant/fragrance ingredient in the perfumery industry, where it can function as a fragrance component and may act as a fixative in certain formulations. In cosmetics and personal care, it may contribute as a fragrance ingredient; in household products such as cleaners and detergents, it can be included to impart scent. In industrial manufacturing, alpha-Amyrenone may serve as a fragrance intermediate for the synthesis of other aroma compounds. In coatings and inks, it can be incorporated as an aroma additive. Uses are subject to local regulations and formulation limits.
