Quality Control

Our 2,2'-Ethylenedianiline is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatographic purity assays and impurity profiling, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee 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). This material is light-sensitive and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation to maintain optimal purity and prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials.
