  • Applications

    1-Hydroxydecan-3-one (CAS 67633-95-8) is a long-chain hydroxy ketone that is primarily used as an intermediate in fragrance and flavor chemistry. In perfumery, it serves as an odorant precursor and a building block for more complex scent molecules; in cosmetics and personal care, it is utilized as a fragrance ingredient or specialty intermediate in formulations; in household products, it may contribute to aroma profiles in cleaners and detergents. In industrial manufacturing, it is employed as a synthetic intermediate for the production of other specialty chemicals. In coatings and inks, it can function as a reactive intermediate or additive related to fragrance formulations. Use is subject to local regulations and formulation limits.
