Quality Control

Our Calcium(II) Bis(trifluoromethanesulfonyl)imide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration, impurity profiling by ion chromatography (IC) and HPLC, and moisture content determination (Karl Fischer). A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific impurity levels is provided with every shipment to ensure compliance with your research and production specifications.

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 product is hygroscopic (moisture-sensitive) and must be handled under a dry, inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong acids, strong bases, and strong oxidizing agents.
