  • Applications

    Kuwanon Y (CAS 105016-28-2) is a natural polyphenolic compound that is typically studied for its antioxidant properties and potential to act as a formulation stabilizer in cosmetics and personal care products, helping resist oxidative degradation and light-induced breakdown. It is also evaluated for use in food processing and packaging as a natural stabilizing additive and antioxidant; in polymers, plastics, coatings, and inks it may be considered as a stabilizer or color-supporting additive to improve oxidative durability and appearance. In pharmaceutical research and synthetic chemistry, it serves as a polyphenol scaffold often used as an intermediate or reference compound in organic synthesis. In agriculture and food processing, its antimicrobial/antifungal activity has been investigated for potential natural-biocide applications, subject to regulatory limits and formulation constraints.
