Quality Control

Our Dihydrosenkyunolide C is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and spectroscopic methods (NMR, MS) for structural confirmation, to ensure it meets the stringent requirements for research and pharmaceutical use. A Certificate of Analysis (COA) detailing all test results is 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
