Quality Control

Our Procyanidin A2 is produced under strict quality management protocols. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent requirements for research and commercial use. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere for long-term stability, as the compound is easily oxidized and light-sensitive. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
