Quality Control

Our 16 α-Ethyl-19-Nor-4-Pregnene-3,20-Dione-21-Al is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, confirming compliance with customer specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature, typically between 15°C and 25°C. The material is light-sensitive and easily oxidized; prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and purity.
