Quality Control

Our 2,5-Dichloroisophthalic Acid Dichloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, open flames, and incompatible materials such as water, alcohols, bases, and strong oxidizing agents.
