Description

Eupalitin-3-o-Galactoside(Rg) is a specific flavonoid glycoside compound, a derivative of eupalitin. This high-purity reference standard is critical for analytical and research applications where precise chemical identity and purity are paramount. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, nutraceutical, and botanical extract industries for method development, validation, and as a calibration standard.

Application

• Pharmaceutical Reference Standard: Used for the identification, assay, and impurity profiling of flavonoid-based drugs and herbal medicinal products in compliance with pharmacopeial methods (e.g., USP, EP).
• Biochemical Research: Serves as a key reagent in studies investigating the biological activity, metabolism, and pharmacokinetics of flavonoid compounds.
• Quality Control in Nutraceuticals: Acts as a quantitative marker for standardizing and authenticating botanical dietary supplements and functional food ingredients containing related flavonoids.
• Analytical Method Development: Essential for developing and validating chromatographic methods (HPLC, LC-MS) for the separation and detection of complex flavonoid mixtures.
• Academic Research: Employed in universities and research institutes for synthetic chemistry, natural product isolation, and structural elucidation projects.
