Description

Quercetin 5-Glucoside is a specific glycosylated derivative of the potent flavonoid quercetin. This compound is valued for its enhanced bioavailability and stability compared to its aglycone form, making it a critical ingredient for advanced nutraceutical and pharmaceutical formulations. It is primarily sought by manufacturers in the dietary supplement, functional food, and cosmeceutical industries seeking to leverage its antioxidant and bioactive properties.

Application

• Dietary Supplements & Nutraceuticals: A key bioactive ingredient in capsules, tablets, and powders targeting antioxidant support, immune health, and anti-inflammatory benefits.
• Functional Food & Beverage Fortification: Used to enhance the nutritional profile of health drinks, sports nutrition products, and fortified food items.
• Cosmeceutical & Skincare Formulations: Incorporated into serums, creams, and lotions for its potential anti-aging and skin-protective effects against environmental stressors.
• Pharmaceutical Research & Development: Serves as a reference standard and an active pharmaceutical ingredient (API) intermediate in preclinical studies for metabolic and inflammatory conditions.
• Natural Colorant & Stabilizer: Can function as a natural colorant and antioxidant to improve the shelf-life and appearance of certain product categories.

Quality Control

Our Quercetin 5-Glucoside is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, UV), to ensure it meets stringent specifications for nutraceutical and research applications. Certificates of Analysis (COA) documenting purity, heavy metals, residual solvents, and microbiological parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and potency.
