Quality Control

Our production of Cyclopropanecarbonyl Chloride, 2,2-Dimethyl-3-(3-Thienyl)- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for research and scale-up applications. All materials are characterized by advanced analytical techniques including NMR, HPLC, and GC-MS. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

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 and reactivity as an acid chloride, it should be handled under an inert atmosphere (e.g., nitrogen or argon) for prolonged storage and opened only in a moisture-free environment. Recommended storage temperature is 2-8°C for long-term stability.
