Quality Control

Our production of 1,1,2,2,3,3,4,4-Octafluoro-4-(1,1,2,2-Tetrafluoro-2-Sulfinoethoxy)-1-Butanesulfinic Acid, Dipotassium Salt adheres to a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity, KF titration for moisture, and ICP-MS for heavy metal traces, to ensure it meets precise customer specifications and high-purity standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every 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). This material is moisture-sensitive (hygroscopic) and contains fluoride/strong alkali components; it must be kept away from strong acids and stored under an inert atmosphere (e.g., nitrogen or argon) for long-term stability to prevent oxidation and hydrolysis.
