Quality Control

Our 4,4-Dichloro-1,1,2,3,3,4-Hexafluoro-1-Butene is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency meet the high standards required for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profiles, and physical properties is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and reactive metals. Due to its highly volatile nature, ensure containers are kept tightly sealed to prevent evaporation and potential pressure buildup. Recommended storage temperature is between 2°C and 25°C.
