Quality Control

Our 5α-Pregn-9(11)-En-12-One is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for pharmaceutical research and development. Each batch undergoes comprehensive analytical testing, including HPLC for assay and related substances. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which may affect stability and performance.
