Quality Control

Our Dimethyl(Pentafluorophenyl)Silanol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (¹H, ¹⁹F, ¹³C), FT-IR, GC/HPLC for purity, and Karl Fischer titration for water content, to ensure it meets precise customer specifications. Comprehensive Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation. Keep away from incompatible materials such as strong acids, bases, and oxidizing agents.
