Quality Control

Our Cyclopropanecarbonyl Chloride, 2,2-Dimethyl-3-(4-Methyl-1,3-Pentadienyl)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of research and process chemistry. Certificates of Analysis (COA) with detailed chromatographic and spectroscopic data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and classification as a strong acid/organic solvent, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
