Quality Control

Our E-2,4,4,4-Tetrafluoro-2-Butene is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, GC-MS, and NMR, to ensure high purity and consistent composition. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat sources and open flames. Recommended storage temperature is between 2°C and 8°C to minimize vapor pressure and maintain stability. Keep container tightly sealed when not in use.
