Quality Control

Our Cyclopropanecarbonyl Chloride, 3-(2-Chloroethenyl)-2,2-Dimethyl- (9Ci) is produced 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 advanced synthetic applications. Certificates of Analysis (COA) detailing purity, impurities, and physical characteristics are available upon request to support your quality and regulatory documentation.

Storage

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