Quality Control

Our [(Cholest-5-Ene-3β,7β-Diyl)Bis(Oxy)]Bis(Trimethylsilane) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure high chemical purity and structural identity. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to support your quality assurance and regulatory 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, which can compromise product integrity. For long-term storage, consider using desiccants or an inert atmosphere.
