Quality Control

Our 20,21-[(Butylboranediyl)Bis(Oxy)]Pregna-5,17(20)-Dien-3β-Ol is manufactured under strict quality management systems. 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 use. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

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 (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
