Quality Control

Our production of Cyclopropanecarbonyl Chloride, 2,2-Dimethyl-3-(3-Thienyl)-, trans- (9Ci) adheres to stringent quality management protocols to ensure batch-to-batch consistency and reliability for your critical syntheses. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all relevant specifications to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and acid chloride nature, the container must be kept under an inert atmosphere (e.g., nitrogen or argon) and sealed securely to prevent moisture ingress and decomposition. Keep away from strong bases and oxidizing agents.
