Quality Control

Our Silacyclopropane, 2,3-Dichloro-1,1-Dimethyl- (9Ci) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and batch-to-batch consistency suitable for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong acids and incompatible organic solvents.
