Quality Control

Our 1,1-Cyclopropanedicarbonyl Chloride, 2-Methyl- (6Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets the high standards required for sensitive synthetic applications. Certificates of Analysis (COA) detailing purity, impurities, and physical properties are provided with every shipment.

Storage

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