Description

Procyanidin B7 is a specific dimeric proanthocyanidin, a class of naturally occurring polyphenolic compounds known for their potent antioxidant properties. This high-purity standard is critical for research and development, enabling precise quantification and biological activity studies. It serves as an essential reference material for analytical laboratories and formulators in the nutraceutical, cosmetic, and pharmaceutical industries seeking to standardize and validate their products.

Application

• Analytical Reference Standard: Used for the identification, quantification, and method validation of procyanidins in complex matrices via HPLC, LC-MS, or other chromatographic techniques.
• Nutraceutical & Dietary Supplement Research: Investigated for its potential bioactive effects, including antioxidant capacity, cardiovascular support, and metabolic health applications.
• Cosmetic & Skincare Formulation: Incorporated into anti-aging and protective skincare products for its ability to neutralize free radicals and support skin health.
• Pharmaceutical Development: Studied as a lead compound or active pharmaceutical ingredient (API) intermediate for its various purported therapeutic properties.
• Food & Beverage Science: Employed in research to understand the contribution of specific procyanidins to the flavor, color stability, and health benefits of foods like cocoa, grapes, and apples.
• Biochemical & Pharmacological Studies: Serves as a precise tool in vitro and in vivo studies to elucidate mechanisms of action, bioavailability, and metabolism of procyanidin compounds.

Quality Control

Our Procyanidin B7 is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, MS), to ensure it meets the high standards required for research and development. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation. Keep the container in a cool, dry, and well-ventilated area. For long-term storage, desiccate at -20°C.
