Quality Control

Our production of Benzene, 1-Isocyanato-4-(2-Isocyanato-2-Methylpropyl)- (9Ci) adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure high purity, consistent reactivity, and compliance with relevant industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and performance for your critical applications.

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 / 59-77°F). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent reaction with atmospheric moisture. Isolate from heat, open flames, and incompatible materials such as alcohols, amines, and strong bases.
