  • Applications

    Kuwanon H (CAS 76472-87-2) is a prenylated flavonoid isolated from Morus species that has been studied mainly for antioxidant and antimicrobial activities. In practical terms, it may be used as a natural antioxidant and stabilizing additive in cosmetics and personal care formulations, as well as a functional ingredient to help preserve the shelf life of certain foods and beverages where permitted. It can also serve as a stabilizer for coatings, inks, and polymer formulations by improving oxidative resistance and color retention. Additionally, Kuwanon H is evaluated as a bioactive lead compound in natural product research and may function as an intermediate in the synthesis of related flavonoids. Its use, if any, will be subject to local regulations and formulation limits.
