Quality Control

Our 2,3,5,6-Tetrachloroterephthaloyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency and high purity, meeting the stringent requirements of industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee supply reliability and technical compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area 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 bases, alcohols, and water.
