  • Applications

    Tetrahydrodemethoxycurcumin (CAS 149579-07-7) is a hydrogenated analogue of the curcuminoids and is commonly evaluated for real-world applications across several sectors: as an antioxidant stabilizer in cosmetics and personal care formulations; as a colorant or stabilizing additive in polymers and plastics; as a pigment-related additive in coatings and inks; and as an intermediate in pharmaceutical research and synthetic chemistry for developing related curcuminoid derivatives.
