  • Applications

    Allohimachalol (CAS 19435-77-9) is a sesquiterpene alcohol that is typically considered a fragrance-related odorant. In fragrance and perfumery applications, it is used as an odorant or scent component; in cosmetics and personal care, it may serve as a fragrance ingredient or enhance the scent of products such as cleansers, moisturizers, and shampoos. In household products and cleaners, it can be added to improve odor and consumer perception. In coatings, finishes, and inks, it can be used as a fragrance additive to tailor the odor profile of the product. In industrial manufacturing, it may function as an intermediate or building block for fragrance-related syntheses, subject to local regulations and formulation limits.
