Quality Control

Our 4,5-Dichloroisophthalic Acid Dichloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

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). This material is hygroscopic (moisture-sensitive) and reacts with water and strong bases; ensure containers are sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to maintain product integrity. Keep away from heat, open flames, and incompatible materials.
