Quality Control

Our (1,1,2,2-Tetrafluoroethoxy)Difluoroacetyl Fluoride is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including NMR, GC, and IR spectroscopy. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent derivative, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from moisture, bases, and oxidizing agents.
