Quality Control

Our Magnesium Trifluoromethanesulfonimide is produced under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and moisture content determination. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We can support compliance requirements for various industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from incompatible materials such as strong bases and fluorides.
