Quality Control

Our N,N'-Bis(Chlorodimethylsilyl)-α,α-Dimethylsilanediamine is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency for your critical applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles 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). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity. Keep away from strong bases and incompatible materials.
