Quality Control

Our production of Cyclopropanecarbonyl Chloride, 2,2-Dichloro-1-Ethyl- (9Ci) adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every 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 place. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Recommended storage temperature is 2-8°C for long-term stability.
