Quality Control

Our Cyclopropanecarbonyl Chloride, 2,2-Dichloro-1-Methyl- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopic methods, to ensure high purity and batch-to-batch consistency suitable for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and classification as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from atmospheric moisture. Keep away from heat, sparks, open flames, and incompatible materials such as bases, alcohols, and amines.
