Quality Control

Our 5Alpha-Androstan-3-One, 17Beta-Hydroxy-1Alpha,17-Dimethyl- 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 exacting standards for research and synthesis. A Certificate of Analysis (COA) detailing specific results for purity, related substances, and residual solvents is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
