Quality Control

Our Procyanidin C1 is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for research and formulation use. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, related substances, and residual solvents.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. For short-term use, store at 2-8°C. The material is easily oxidized and light-sensitive; allow the sealed container to reach room temperature before opening to prevent moisture condensation.
