Quality Control

Our Osaterone Acetate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, residual solvent analysis, and identity confirmation by IR and NMR, to ensure it meets stringent specifications for pharmaceutical research. 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 place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider using desiccants.
