Quality Control

Our 1,4-Benzenediamine,n-Ethyl-n-Methyl-(9Ci) is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay (HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure it meets the high standards required for industrial and research applications. A Certificate of Analysis (COA) documenting purity, physical properties, and test results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen or argon) to preserve stability and prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials.
