Quality Control

Our 1,2-Benzenedicarbonyl Dichloride,4,5-Dibromo is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each 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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation.
