Quality Control

Our 17Beta-Hydroxy-1Alpha-Methylandrost-4-Ene-3-One is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay, related substances, and residual solvents, supporting compliance with cGMP and other relevant quality guidelines for pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. Recommended storage temperature is 2-8°C for long-term stability.
