Quality Control

Our (Di-n-Octylmethylsilyl)Ethyltrichlorosilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance protocols.

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 material is hygroscopic (moisture-sensitive) and reacts with strong acids and organic solvents; ensure containers are kept tightly sealed under an inert atmosphere such as nitrogen or argon to prevent degradation.
