Quality Control

Our Cholest-7-En-6-One derivative is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and spectroscopic identification (NMR, IR, MS), to ensure it meets exacting standards for research and development. Certificates of Analysis (COA) with full characterization data 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 and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation.
