Quality Control

Our Perfluoropolyether Diacyl Fluoride is manufactured under stringent quality systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including NMR (19F, 1H), FT-IR, and GC-MS to confirm identity and assay. Certificates of Analysis (COA) detailing purity, moisture content, and acid fluoride content are provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Isolate from incompatible materials such as water, alcohols, amines, and strong bases.
