Quality Control

Our Methylphenyldivinylsilane is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, confirming compliance with agreed specifications. Our quality system supports traceability and meets the demands of industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain purity. Recommended storage temperature is 2-8°C for long-term stability.
