Quality Control

Our Allyltris(Trimethylsiloxy)Silane is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing key specifications such as assay, identity, and moisture content to support your quality assurance processes.

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 compound is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from atmospheric moisture.
