Quality Control

Our Osaterone is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and related substances, to meet the stringent requirements of pharmaceutical R&D. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment and is available upon request.

Storage

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