Quality Control

Our Divinyldichlorosilane is produced under stringent quality control protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including gas chromatography (GC) and NMR spectroscopy, to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with each shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and moisture-sensitive nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity. Recommended storage temperature is 2-8°C.
