Quality Control

Our n-Ethyl-p-Phenylenediamine is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including purity assay and impurity profiling, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 properties of being light-sensitive and easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize degradation. Keep away from strong oxidizing agents.
