Quality Control

Our 21,23-Epoxy-3β,12β,23-Tris[(Trimethylsilyl)Oxy]-24-Nor-5β-Chola-20,22-Dien-14β-Ol is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

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 an inert atmosphere.
