Quality Control

Our Cyclopropanecarbonyl Chloride, 2,2-Dichloro-1,3-Dimethyl-, cis- (9Ci) is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including chiral purity analysis, to ensure it meets the high standards required for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and consistency for your critical R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 15-25°C). This material is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; ensure the container is kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from heat, sparks, and open flame.
