Quality Control

Every batch of our Cyclopropanecarbonyl Chloride, 2-Ethyl-2,3,3-Trimethyl- (9Ci) is produced and tested under strict quality management protocols to ensure high purity and batch-to-batch consistency. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases, alcohols, and amines. Due to its hygroscopic and moisture-sensitive nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability.
