Quality Control

Our production of Dimethyl(Bis(1,1,2,2-Tetrafluoro-2-[1,2,2,2-Tetrafluoro-1-(Trifluoromethyl)Ethoxy]Ethyl))Silane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including NMR, FT-IR, and GC-MS, to confirm structural identity and purity. We provide detailed Certificates of Analysis (COA) with each shipment, ensuring traceability and compliance with your material specifications and internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored under a dry, inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended storage temperature is 2-8°C to maintain long-term stability. Allow the container to reach room temperature before opening to prevent moisture condensation.
