Quality Control

Our Tetra-p-Vinyl-Silan is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR), to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to guarantee compliance with your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Recommended storage temperature is between 2°C and 8°C (under refrigeration) to maintain optimal stability and prevent premature polymerization. The container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) due to its reactive vinyl groups.
