Quality Control

Our 1,4-Bis(Isocyanatomethyl)-2,3,5,6-Tetrachlorobenzene is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure consistent purity, reactivity, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, isocyanate content, and impurity profiles are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and polymerization. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and water.
