Quality Control

Our Cyclopropanecarbonyl Chloride, 1-(4-Chlorophenyl)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; therefore, it must be kept under an inert atmosphere (e.g., nitrogen or argon) and away from incompatible materials.
