Quality Control

Our 5β-Pregnane-3,15,20-Trione is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods. Certificates of Analysis (COA) detailing all test results are provided with every shipment to support your quality assurance and regulatory needs.

Storage

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