Quality Control

Every batch of Cyclopropanecarbonyl Chloride, 3-Ethenyl-2,2-Dimethyl-, (1R,3R)- (9Ci) is manufactured under strict quality management systems. Our products undergo rigorous analytical testing, including chiral HPLC and NMR, to ensure high enantiomeric purity and chemical identity. Certificates of Analysis (COA) with detailed specifications are provided for each lot to support your R&D and regulatory requirements.

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 and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from strong bases, oxidizers, and sources of ignition.
