Description

5,7-dihydroxy-2-[3-hydroxy-4-(2-hydroxyethoxy)phenyl]-3-[(2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-[[(2R,3R,4R,5R,6S)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxymethyl]oxan-2-yl]oxychromen-4-one is a high-purity, complex flavonoid glycoside valued for its specific biological activity and structural properties. This compound is critical for advanced research and development in life sciences, where precise molecular structure and purity are paramount. It is primarily sought by manufacturers and research institutions in the pharmaceutical, nutraceutical, and high-end cosmetic industries for use as a reference standard or active ingredient.

Application

• Pharmaceutical Reference Standard: Used for the identification, purity assessment, and quantification of active pharmaceutical ingredients (APIs) in method development and quality control laboratories.
• Biochemical Research: Serves as a key intermediate or probe in studying enzymatic pathways, receptor binding, and other cellular mechanisms due to its specific glycosidic structure.
• Nutraceutical Formulation: Incorporated into advanced dietary supplements targeting specific health benefits, leveraging its flavonoid-based activity.
• Cosmetic Actives: Used in premium skincare formulations for its potential antioxidant and skin-conditioning properties.
• Analytical Chemistry: Employed as a calibration standard in High-Performance Liquid Chromatography (HPLC) and Liquid Chromatography-Mass Spectrometry (LC-MS) analyses.
