  • Applications

    Morin, CAS 480-16-0, is a natural flavonoid with several practical applications across chemical, cosmetic, and materials industries. In cosmetics and personal care, it is commonly regarded as an antioxidant additive that can help stabilize formulations and protect color. In analytical chemistry and materials science, morin is used as a metal-chelating reagent and as a reference compound in metal-detection systems (e.g., for Al3+ and Fe3+) using colorimetric or spectroscopic methods. In pharmaceutical research and chemical synthesis, morin is considered a lead compound and/or a versatile building block for the synthesis of other flavonoids and for exploratory biological activity studies. In the plastics and polymer sector, morin is evaluated as a natural additive with antioxidant interest to improve stability of formulations. These applications are investigational and may depend on local regulations and formulation limits.
