Quality Control

Our production of 1-Chloro-1-Ethenylsiletane adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis using advanced techniques such as GC, NMR, and Karl Fischer titration. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment, ensuring full traceability and compliance with customer specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening and should be allowed to reach ambient temperature before use to prevent moisture ingress.
