Quality Control

Our production of 2,2,3,3,9,9,10,10-Octamethyl-4,8-Dioxa-3,9-Disilaundecan-6-Amine adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including assay (GC/HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting purity, physical properties, and lot-specific data are available upon request.

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). This amine-functional siloxane is moisture-sensitive (hygroscopic); keep the container tightly sealed under an inert atmosphere (nitrogen) to prevent degradation and maintain product integrity.
