Description

Afzelechin 3-o-Xyloside is a naturally occurring flavan-3-ol derivative, a specific type of polyphenol compound. This high-purity reference standard is critical for analytical research, quality control, and the development of nutraceutical and pharmaceutical products. It is primarily sought by researchers and manufacturers in the life sciences, natural product chemistry, and dietary supplement industries for its role as a bioactive marker and potential health-beneficial agent.

Application

• Analytical Reference Standard: Used as a primary standard for the qualitative and quantitative analysis (e.g., HPLC, LC-MS) of complex plant extracts and botanical products.
• Phytochemical & Natural Product Research: Serves as a key compound for studying the biosynthesis, metabolism, and biological activities of flavan-3-ols and related polyphenols.
• Nutraceutical & Dietary Supplement Formulation: Employed in the research and development of standardized herbal extracts where afzelechin derivatives are target active constituents.
• Cosmeceutical Research: Investigated for potential antioxidant and skin-protective properties in advanced cosmetic and personal care formulations.
• Food & Beverage Science: Used in studies analyzing the polyphenol content and antioxidant capacity of foods like tea, cocoa, and certain fruits.
• Bioavailability & Pharmacokinetic Studies: Acts as a probe to understand the absorption, distribution, metabolism, and excretion (ADME) of specific flavan-3-ol structures.

Quality Control

Our Afzelechin 3-o-Xyloside is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and spectroscopic methods (NMR, MS) for structural confirmation, to ensure it meets the exacting standards required for research and development. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as specified on the label or COA. This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to minimize exposure to atmospheric humidity.
