Description

5,7-Dimethoxy-2-[3-methoxy-4-[(2-O,3-O,4-O,6-O-tetramethyl-β-D-glucopyranosyl)oxy]phenyl]-6-[(2-O,3-O,4-O,6-O-tetramethyl-β-D-glucopyranosyl)oxy]-4H-1-benzopyran-4-one is a specialized, high-purity flavonoid glycoside derivative with a complex, fully methylated sugar moiety. This compound is valued for its role as a key reference standard and synthetic intermediate in advanced pharmaceutical and nutraceutical research. It is primarily sought by R&D and quality control laboratories in the pharmaceutical, biotechnology, and natural product chemistry sectors for method development and analytical verification.

Application

• Pharmaceutical Reference Standard: Used for the identification, assay, and impurity profiling of related active pharmaceutical ingredients (APIs) in HPLC and LC-MS methods.
• Biochemical Research: Serves as a substrate or inhibitor in enzymatic studies targeting glycosidase or flavonoid metabolic pathways.
• Natural Product Synthesis: Acts as a crucial intermediate in the semi-synthesis or structural modification of complex flavonoid glycosides for bioactivity screening.
• Analytical Chemistry: Employed as a high-purity calibrant for quantitative analysis in pharmacokinetic and metabolomic studies.
• Nutraceutical Standardization: Used to standardize and authenticate complex botanical extracts intended for dietary supplements.
