Quality Control

Our 2-Cyclopropene-1,1-Dicarbonyl Dichloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

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, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong bases and oxidizing agents.
