Quality Control

Our Cholestane-3,7,25,26-Tetrol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting purity, assay, and impurity profiles.

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 an inert atmosphere.
