Quality Control

Our production of Cyclopropanecarbonyl Chloride, 3-(1-Butenyl)-2,2-Dimethyl- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and reliability for your synthetic processes. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity, identity, and impurity profiles. Our quality management system is designed to support cGMP and ISO standards for advanced chemical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature and classification as a strong acid/organic solvent, it must be kept under an inert atmosphere (e.g., nitrogen or argon) and separated from bases and oxidizing agents. Recommended storage temperature is 2-8°C for long-term stability.
