  • Applications

    2-Hydroxy-2-methyl-1-phenylpropan-1-one, CAS 7473-98-5, is commonly used as an intermediate in fragrance chemistry and as a synthetic building block in pharmaceutical-related synthesis; it may function as an aroma ingredient or a fixative in cosmetics and personal care products, and in household and cleaning products where a defined scent is desired. It can serve as a precursor to more complex fragrance molecules and as a reactive intermediate in industrial chemical syntheses. In coatings and inks, it may be explored as an aroma-related additive or a starting point for related derivatives, subject to formulation limits and regulatory compliance.
