Quality Control

Our Cyclopropanecarbonyl Chloride, 3-(2-Chloro-1-Propenyl)-2,2-Dimethyl-, trans- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity, correct stereochemistry, and the absence of critical impurities. Certificates of Analysis (COA) detailing identity, purity, and specific test results are available for every shipment to support your quality assurance and regulatory needs.

Storage

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