Quality Control

Our Cyclobutanecarbonyl Chloride, 1-Hexyl- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC/HPLC for purity and NMR/IR for structural confirmation, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from strong bases, oxidizers, and sources of ignition.
