Description

3,7-Diglucosylquercetin CAS NO 6892-74-6 is a specific glycosylated derivative of the potent flavonoid quercetin, where two glucose molecules are attached at the 3 and 7 positions. This structural modification significantly enhances its water solubility and bioavailability compared to the aglycone, making it a highly valuable compound for advanced nutraceutical and pharmaceutical research. It is primarily sought after by manufacturers in the dietary supplement, functional food, and cosmeceutical industries for its potential antioxidant and anti-inflammatory properties.

Application

• Dietary Supplements & Nutraceuticals: As a key bioactive ingredient in formulations targeting oxidative stress and cellular health.
• Functional Food & Beverage Fortification: Used to enhance the nutritional profile of health-focused products like energy bars, drinks, and yogurts.
• Cosmeceutical & Skincare Products: Incorporated into serums, creams, and lotions for its potential anti-aging and skin-protective benefits.
• Pharmaceutical Intermediates: Serves as a precursor or active ingredient in the development of novel therapeutic agents.
• Biochemical & Life Science Research: Utilized as a standard or reagent in studies investigating flavonoid metabolism, bioavailability, and biological activity.
• Veterinary Health Products: Applied in premium animal nutrition and health supplements.
