Quality Control

Our N,N'-Bis(Trimethylsilyl)Ethylenediamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) with detailed specifications are provided for every shipment, ensuring full traceability and compliance with your internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) and highly volatile nature, store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, and open flames.
