  • Applications

    7-Hydroxy-6-Hydromelodienone is used primarily as a fragrance ingredient and a precursor in fragrance synthesis, contributing specific aroma notes and enabling preparation of related scent compounds. It may be employed in cosmetics and personal care formulations as a fragrance additive, and in household and cleaning products to impart distinctive odor profiles. In industrial manufacturing, it is evaluated as an aroma chemical intermediate and can be incorporated into scented polymers, plastics, coatings and inks as an odorant component.
