Quality Control

Our 1,2-Difluoroethylene is produced and handled under stringent quality management systems. Each batch is analyzed to ensure it meets precise specifications for purity and composition. Certificates of Analysis (COA) detailing gas chromatography (GC) purity, isomer ratio, and impurity profiles are available upon request to support your quality assurance and regulatory 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 and stored in a location compliant with local regulations for compressed gases. Keep container tightly sealed when not in use to prevent loss and contamination.
