Description

(-)-Epicatechin-Pentaacetate is a high-purity, fully acetylated derivative of the natural flavonoid (-)-epicatechin. This chemical modification enhances its stability and lipophilicity, making it a valuable intermediate for advanced research and synthesis. It is primarily utilized by pharmaceutical, nutraceutical, and life science research organizations for developing and studying bioactive compounds, particularly those targeting oxidative stress and metabolic pathways.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel therapeutic agents and prodrugs.
• Biochemical Research: Used as a standard or probe in studies of flavonoid metabolism, bioavailability, and acetylated polyphenol activity.
• Nutraceutical Development: Serves as a precursor or model compound for developing stabilized flavonoid ingredients with enhanced absorption.
• Reference Standard: High-purity material for analytical method development and quality control in dietary supplement and natural product manufacturing.
• Cosmeceutical Actives: Investigated for use in advanced skincare formulations targeting antioxidant and anti-aging benefits.
