  • Applications

    Curcumadiol (CAS 31946-48-2) is viewed as an organic synthesis intermediate for applications in perfumery and cosmetics, serving as a building block for fragrance compounds and color-related ingredients; in the polymer and plastics sector it can function as a polyol component or the precursor for coating systems and color architectures; in coatings and inks it may act as a dye precursor or color intermediate; in pharmaceutical and agrochemical development it is evaluated as a synthetic building block for biologically active frameworks; and depending on local regulations, it may be considered a functional additive or stabilizer/antioxidant in formulated products.
