Quality Control

Our 3,17α-Dihydroxy-1,3,5(10)-Estratrien-16-One o-Methyl Oxime is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification (IR, NMR), purity assay (HPLC), and control of related substances, to ensure it meets the stringent requirements for pharmaceutical R&D and fine chemical synthesis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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.
