Quality Control

Our production of N,N'-[(2,4,4,6,8,8-Hexamethylcyclotetrasiloxane-2,6-Diyl) Bis(Oxy)] Bis[n-Ethyl-Ethanamine] adheres to a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including NMR (¹H, ¹³C, ²⁹Si), FT-IR, and GC or HPLC analysis, to confirm chemical identity and assay. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting key parameters such as purity, water content, and specific impurity profiles. Our quality commitment ensures the material meets the stringent requirements for research and industrial-scale applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame. For long-term storage, consider using an inert atmosphere (e.g., nitrogen or argon) to maintain product integrity.
