Quality Control

Our Ent-16S,17-Dihydroxyatisan-3-One is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic identification (IR, NMR), to ensure it meets stringent specifications for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 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.
