Quality Control

Our 2-Cyclopropene-1-Carbonyl Chloride, 2-Butyl- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming the product meets the agreed specifications for your research or production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled 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) after opening to prevent moisture absorption and decomposition. Keep away from strong bases and oxidizing agents.
