Quality Control

Our 4,4'-Methylenebis[2,6-Dichloroaniline] is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for polymer-grade applications. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and melting point is provided with every shipment to guarantee consistency and reliability for your production processes.

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). Keep away from heat, open flames, and incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, containers should be kept in opaque packaging or amber glass.
