Quality Control

Our 21,24-Epoxy-3β-Hydroxy-9β,19-Cyclolanostane-24-Methanol is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high chemical purity and structural identity. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and analytical results is provided with each 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. For long-term storage, consider using desiccants.
