Quality Control

Our Dibutyltin Bis(Trifluoromethanesulfonate) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling, to ensure it meets high-purity standards for catalytic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and moisture content is provided with every shipment.

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 must be handled under a dry inert atmosphere (e.g., nitrogen or argon) to prevent decomposition.
