Quality Control

Our Tenacissoside A is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment and spectroscopic methods (NMR, MS) for structural confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing all specifications are available upon request.

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 desiccants or inert atmosphere.
