Quality Control

Our production of 1,3-Divinyl-1,3-Dimethyl-1,3-Dichlorodisiloxane adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including GC, NMR, and FTIR analysis, to verify identity and composition. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and highly volatile. It should be handled and stored under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain purity. Keep away from strong acids and organic solvents.
