Quality Control

Our 1,1-Cyclopropanedicarbonyl Dichloride is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, HPLC, and NMR to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical parameters is provided with 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, and well-ventilated place at 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) to prevent hydrolysis. Keep away from strong bases, alcohols, and water.
