Quality Control

Our 17Beta-Hydroxyandrost-4-En-3-One Undecenoate is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including identification (IR, NMR), purity assay (HPLC), and control of specific impurities, to ensure it meets stringent specifications for pharmaceutical intermediates. A Certificate of Analysis (COA) detailing all test results 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 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.
