Quality Control

Our Procyanidin B2 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 research and commercial use. Certificates of Analysis (COA) detailing purity, residual solvents, and heavy metals are provided with every shipment and are available upon request.

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 easily oxidized (store under inert atmosphere) and is light-sensitive (store away from light). Keep container tightly sealed in a dry environment to minimize moisture absorption.
