Quality Control

Our 3,4'-Diamino-4-Nitrodiphenyl Ether is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to store the material under an inert atmosphere for long-term preservation and to minimize degradation.
