Quality Control

Our production of Potassium Nonafluorobis(Trifluoromethyl)Cyclohexanesulphonate adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and ion chromatography, to ensure high purity and batch-to-batch consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, impurity profile, and moisture content. We support cGMP and ISO 9001 compliant manufacturing upon request for critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) in a desiccator for long-term storage to prevent degradation. Keep away from strong acids, strong bases, and incompatible materials.
