Quality Control

Our (20ξ,22R)-2β,3β,14,20,22-Pentahydroxy-5β-Cholesta-7,24-Dien-6-One is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic methods (NMR, IR, MS) for structural confirmation, to ensure identity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, and custom purity grades are available to meet specific research or synthesis requirements.

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 nature, the container should be kept in a desiccated environment to prevent moisture absorption. For long-term storage, consider inert gas purging.
