Quality Control

Our production of 1-Chloromethyl-2,4-Diisocyanatobenzene adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets precise customer and industry specifications. Certificates of Analysis (COA) documenting purity, physical characteristics, and safety data are provided with each shipment to guarantee supply chain transparency and product consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from moisture absorption. Isolate from strong acids, bases, and incompatible organic solvents.
