Quality Control

Our (E)-1,2-Difluoroethylene is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) and FTIR spectroscopy, to ensure high purity and isomeric consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and gaseous nature, store in a cool, well-ventilated area away from heat, sparks, and open flames. Cylinders should be secured upright in a dedicated gas storage area. Keep container tightly sealed under appropriate pressure when not in use.
