  • Applications

    Nepetin (CAS 520-11-6) is a flavone that can function as a chemical intermediate in the synthesis of flavonoid derivatives for pharmaceutical and agrochemical applications. In cosmetics and personal care, it is commonly evaluated for potential roles as an antioxidant and as a color/fragrance-related component. In coatings/inks and plastics, nepetin may serve as a pigment precursor or stabilizing additive for polymer systems. It may also be considered as an intermediate in broader flavonoid synthesis for research and development purposes.
