  • Applications

    5-Hydroxy-2-(4-hydroxyphenyl)-4-oxo-4H-1-benzopyran-7-yl 2,3-di-O-acetyl-beta-D-glucopyranoside (CAS 84323-20-6) is primarily used in pharmaceutical research and related chemical sciences as an intermediate and building block for flavonoid glycoside derivatives; it also serves as a protected glycoside donor/precursor in glycosylation steps during synthetic work. In analytical laboratories, it functions as a reference material for method development and quantification of flavonoid glycosides by LC-MS or HPLC. In perfumery and cosmetics, it may act as a fragrance precursor or delivery system, releasing the aglycone upon hydrolysis, and in formulation research it provides a scaffold for library development of cosmetic ingredients.
