Quality Control

Our production of 1,2-Ethanediamine, N,n-Bis3-(Dimethoxymethylsilyl)Propyl- adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure consistency, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, identity, and impurity profiles are provided to guarantee material traceability and compliance with your technical requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong acids and oxidizing agents.
