Quality Control

Our Tetraethylammonium Fluoride Trihydrofluoride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and moisture content determination, to ensure it meets the high standards required for synthetic applications. A Certificate of Analysis (COA) detailing purity, physical properties, and 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 15-25°C. This material is hygroscopic (moisture-sensitive) and must be handled under inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong acids and incompatible materials.
