Description

Penta-o-Ethylquercetin is a chemically modified derivative of the natural flavonoid quercetin, where all five hydroxyl groups are ethylated. This structural modification enhances its lipophilicity and stability, making it a valuable intermediate for advanced research and development. It is primarily sought by the pharmaceutical, nutraceutical, and cosmetic industries for applications requiring improved bioavailability and metabolic stability of flavonoid-based compounds.

Application

• Pharmaceutical Intermediate: Used in the research and synthesis of novel drug candidates targeting inflammation, oxidative stress, and metabolic disorders.
• Nutraceutical Research: Serves as a key material in developing advanced dietary supplements with enhanced absorption profiles.
• Cosmetic Actives: Incorporated into high-performance skincare formulations for its potential antioxidant and anti-aging properties.
• Biochemical Research: Employed as a standard or probe in studies of flavonoid metabolism, transport, and structure-activity relationships (SAR).
• Functional Food & Beverage: Investigated for use in stabilizing and delivering bioactive flavonoid ingredients in fortified products.
