Description

Quercetin 3-o-β-D-Glucopyranosyl-(1->2)-Rhamnopyranoside is a specific flavonoid glycoside derived from quercetin, a well-known bioactive polyphenol. This compound is valued for its enhanced bioavailability and stability compared to its aglycone form, making it a critical standard and active ingredient for research and development. It is primarily sought by manufacturers and researchers in the nutraceutical, pharmaceutical, and cosmeceutical industries for applications requiring precise, high-purity flavonoid components. Our supply ensures consistent quality and reliable availability for global B2B partners.

Application

• Pharmaceutical Reference Standard: Used as a high-purity certified reference material (CRM) for analytical method development, validation, and quality control of herbal extracts and finished products.
• Nutraceutical Formulation: Incorporated into dietary supplements and functional foods targeting antioxidant support, cardiovascular health, and anti-inflammatory benefits.
• Cosmetic Active Ingredient: Formulated into anti-aging, skin-brightening, and protective skincare products for its antioxidant and UV-protective properties.
• Biochemical Research: Serves as a key reagent in life science research for studying flavonoid metabolism, bioavailability, and specific biological pathways in vitro and in vivo.
• Herbal Extract Standardization: Essential for the quantification and standardization of complex botanical extracts, such as those from Ginkgo biloba or Sophora japonica, to ensure potency and batch-to-batch consistency.

Quality Control

Our Quercetin 3-o-β-D-Glucopyranosyl-(1->2)-Rhamnopyranoside is produced and tested under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial use. Certificates of Analysis (COA) detailing all specifications are available upon request, supporting compliance with cGMP and relevant pharmacopeial guidelines where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a low-humidity environment to prevent degradation.
