Quality Control

Our Cyclopropanecarbonyl Chloride, 2,2,3-Trimethyl- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC/HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as an acid chloride, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases, oxidizers, and moisture.
