Quality Control

Our 2,3-Dichlorohexafluoro-2-Butene is produced and handled under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high purity and consistency suitable for sensitive synthetic applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids, bases, and reactive metals. Due to its highly volatile nature, ensure containers are kept upright and sealed when not in use. Recommended storage temperature is 2-8°C (36-46°F) for extended stability.
