Quality Control

Our Peanut Procyanidin D is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets stringent specifications for research and industrial use. Certificates of Analysis (COA) documenting purity, related substances, and residual solvents are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. This material is easily oxidized; for optimal preservation, storage under an inert atmosphere such as nitrogen or argon is recommended. Keep container tightly sealed when not in use to minimize exposure to moisture and air.
