Quality Control

Our Pregn-5-Ene-7,20-Dione, 3-β-Hydroxy- is produced and tested under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and synthesis applications. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which may affect stability and handling properties.
