  • Applications

    Schaftoside (CAS 51938-32-0), a flavone glycoside found in a range of plants, is primarily used in industry as an intermediate for the synthesis of flavonoid derivatives, as a reference standard for natural product analysis, and as a research reagent for evaluating biological activity; it is also considered in cosmetics as a potential antioxidant or stabilizer in formulations, and data from studies may support quality assessment of plant extracts and related products.
