Quality Control

Our Potassium 2,3,3,3-Tetrafluoro-2-(Heptafluoropropoxy)Propionate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity, KF titration for moisture, and NMR/IR for structural confirmation, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are provided with each shipment.

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, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
