Quality Control

Our Pentafluoro[1,1'-Oxybis[ethane]]phosphorus is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR (1H, 19F, 31P), GC-MS, and FTIR, to confirm identity and purity, typically exceeding 95%. Certificates of Analysis (COA) detailing all test results are provided with every shipment to ensure full traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its classification as a fluoride/strong alkali reactive and highly volatile compound, store in a cool, well-ventilated area, ideally at 2-8°C or as specified on the label. Keep away from moisture, strong bases, and incompatible materials. Containers must be kept tightly sealed and upright to prevent leakage and pressure buildup.
