Quality Control

Our Cyclopropanecarbonyl Chloride, 3-(2-Chloro-1-Propenyl)-2,2-Dimethyl- (9Ci) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

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