Quality Control

Our 17α-Methyl-5β-Androstane-3α,17β-Diol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification (IR, NMR), purity assay (HPLC), and control of specified impurities to ensure it meets rigorous standards for research and synthesis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability, consistency, and compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect stability and purity.
