Quality Control

Our (Oet)2Im-Ntf2 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and Karl Fischer titration, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, water content, and halide levels is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 15-25°C. This product is hygroscopic (moisture-sensitive) and incompatible with strong bases and fluorides. Keep the container tightly sealed under an inert atmosphere such as argon or nitrogen to prevent moisture absorption and degradation.
