Quality Control

Our Cyclopropanecarbonyl Chloride, 1-Ethoxy- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles 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. Due to its hygroscopic and moisture-sensitive nature, containers should be kept sealed under an inert atmosphere (e.g., nitrogen) to prevent decomposition. Recommended storage temperature is 2-8°C for long-term stability.
