Quality Control

Our Octafluorocyclopentene is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed against rigorous internal specifications, which typically include identity confirmation by FT-IR and GC-MS, purity determination by gas chromatography, and quantification of key impurities and moisture. A Certificate of Analysis (COA) detailing all test results is 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 nature, store in a cool, well-ventilated area away from heat sources and ignition points. Recommended storage temperature is between 2°C and 25°C. Cylinders should be stored upright and secured. Keep container tightly sealed when not in use to prevent loss of product and ingress of moisture.
