Quality Control

Our 5-Bromo-2,3-Dihydrobenzo[B]Furan-7-Carbonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for research and process development. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 decomposition.
