  • Applications

    Lactaroviolin (CAS 85-33-6) is typically considered an odorant and fragrance ingredient with potential applications across several industries. In perfumery and cosmetics/personal care, it may function as a fragrance component or note in formulations. In household products, it can be used to impart or enhance scent in cleaners and detergents. It may be evaluated for flavor applications in select culinary-forward aroma profiles. In industrial manufacturing, it can serve as an intermediate in the synthesis of related aroma chemicals. Its use is subject to regulatory requirements and formulation constraints.
