Quality Control

Our 4,4'-Diamino-3,3'-Dinitrodiphenyl Ether is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure high purity, consistency, and traceability. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, impurity profile, and physical characteristics. Our quality commitment ensures the material meets the stringent requirements for advanced synthesis and industrial 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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product quality. Keep away from incompatible materials such as strong oxidizing agents.
