Quality Control

Our Epimestrol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity and identity confirmation, to ensure it meets the stringent requirements for research and pharmaceutical applications. 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 area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
