Quality Control

Every batch of our Cyclopropane, 1,1-Dichloro-2-Isocyanato- (9Ci) is produced and controlled under a strict quality management system. We ensure high purity and batch-to-batch consistency through advanced analytical techniques including GC, HPLC, and NMR. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality and regulatory requirements.

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 (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
