Quality Control

Our (20E,24S)-3β,19-Epoxy-5α-Dammar-20(22)-Ene-3α,11α,24,25-Tetrol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR, MS), to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics is provided with every shipment.

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. For long-term storage, consider using desiccants or storing under an inert atmosphere.
