Quality Control

Our production of Cyclopropanecarbonyl Chloride, 2-(o-Chlorophenyl)- adheres to stringent in-process controls to ensure batch-to-batch consistency and high purity. Each lot is fully characterized using advanced analytical techniques including GC, HPLC, NMR, and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment, supporting cGMP-compliant research and development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a 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 or argon) to prevent hydrolysis. Keep away from strong bases, oxidizers, and sources of ignition.
