Quality Control

Our 3 α-Hydroxy-5 α-Pregna-9(11),16-Diene-20-One is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets stringent specifications for pharmaceutical intermediate use. Certificates of Analysis (COA) documenting all test results are 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.
