  • Applications

    Norartocarpetin (CAS 520-30-9) is a plant-derived flavonoid used as an intermediate in organic synthesis and medicinal chemistry research. In cosmetics and personal care, it is studied as an antioxidant additive and stabilizer to improve formulation stability and product longevity. In polymers and coatings, it is evaluated as an antioxidant/aging stabilizer to enhance resistance to oxidative degradation. It is explored in pharmaceutical research as a lead compound for medicinal chemistry, and in nutraceutical contexts for its antioxidant potential. Its use is subject to local regulations and formulation limits.
