Quality Control

Our production of Bicyclo[2.2.1]Hepta-2,5-Diene-2-Carbonyl Chloride, 3-Methoxy- (9Ci) adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity for research and scale-up applications. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and GC to confirm identity and purity. Certificates of Analysis (COA) detailing all relevant specifications are provided with every shipment.

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 and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents.
