Description

Quercetin 3-o-α-Rhamnopyranosyl-(1-2)-β-Galactopyranoside is a specific, high-purity flavonoid glycoside derived from quercetin, a well-known natural antioxidant. This compound is valued for its enhanced bioavailability and targeted bioactivity compared to its aglycone counterpart, making it a critical intermediate for advanced research and product development. It is primarily sought by manufacturers in the nutraceutical, pharmaceutical, and cosmeceutical industries for formulating high-efficacy supplements, therapeutic agents, and premium skincare products.

Application

• Nutraceutical Ingredient: Used as a key active component in dietary supplements targeting oxidative stress, inflammation, and cardiovascular health.
• Pharmaceutical Research: Serves as a reference standard and a potential active pharmaceutical ingredient (API) intermediate in drug discovery for metabolic and inflammatory diseases.
• Cosmeceutical Formulations: Incorporated into anti-aging and protective skincare products for its potent antioxidant and potential collagen-stabilizing properties.
• Functional Food & Beverage: Applied in the fortification of health-focused foods and drinks to enhance their nutritional profile.
• Biochemical Research: Utilized in laboratory studies to investigate flavonoid metabolism, glycosidase interactions, and cellular signaling pathways.
• Veterinary Supplements: Employed in advanced animal health products for companion and performance animals.
