Quality Control

Our Cyclopropanecarbonyl Chloride, 2,2-Dimethyl-3-(1-Propenyl)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for advanced synthetic applications. Certificates of Analysis (COA) with detailed chromatographic and spectroscopic data are available upon request 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 at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity.
