Quality Control

Our Dihydroisotanshine Ii is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the stringent requirements for research and development use. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability and compliance with your specifications.

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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption and degradation. For long-term storage, consider using desiccants.
