Quality Control

Our 1-Cyclohexene-1-Carbonyl Chloride, 4-(1-Methylethenyl)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the exacting standards required for research and process chemistry. Certificates of Analysis (COA) with detailed chromatographic and spectroscopic data are provided to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. 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. Recommended storage temperature is 2-8°C for long-term stability.
