Quality Control

Our Perfluoro-2-Butene, (Z)- is produced and handled under stringent quality management protocols. Each batch is analyzed to ensure it meets high-purity standards, with typical specifications focusing on identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and gas chromatography results is provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed, properly rated cylinder or container, protected from light and stored in a cool, well-ventilated area. Due to its highly volatile and gaseous nature, containers must be kept upright and secured. Store away from heat sources, open flames, and incompatible materials. The recommended storage temperature is between 15°C and 25°C (59°F and 77°F).
