Quality Control

Our production of 2,2,3,3-Tetrafluoro-3-(trifluoromethoxy)propanoic acid anhydride adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, GC, and FTIR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong bases and fluorides.
