  • Applications

    Ethyl 3-hydroxy-4-methoxybenzoate is primarily used as a fragrance ingredient and as a chemical intermediate in the synthesis of aroma and flavor compounds. It can serve as a scent component in cosmetics and personal care products, as well as in household products and other formulations where odor is desired. In industrial manufacturing, it provides a building block for the preparation of more complex aromatic esters and fragrance-related intermediates used in coatings or inks. It may also be explored as a research intermediate for the development of pharmaceutical or agrochemical derivatives, subject to formulation constraints and local regulations.
