Quality Control

Every batch of 2-Oxabicyclo[2.2.2]Oct-7-Ene-5-Carbonyl Chloride, 3-Oxo-, (1Alpha,4Alpha,5Alpha)- (9Ci) is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the compound meets the high-purity standards required for sensitive synthetic applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment to guarantee traceability and consistency for your R&D and scale-up processes.

Storage

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