  • Applications

    Ambrettolic acid, CAS 506-14-9, is primarily used as an intermediate in fragrance chemistry, serving as a building block for the synthesis of ambrettolide and related macrocyclic musk compounds. It is commonly evaluated for use in perfumery and cosmetic fragrance formulations as a precursor and odor-active component, contributing to warm, musky notes. The compound can function as a starting material for the preparation of esters and other aroma chemicals used in industrial fragrance synthesis, and is sometimes employed in research and development for new fragrance materials, subject to local regulations and formulation limits.
