Quality Control

Our 20,21-(Methylboranediylbisoxy)-5α-Pregn-17(20)-En-3-One is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by spectroscopic methods (NMR, IR), to ensure it meets exacting standards for research and development use. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability, purity, and consistency.

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.
