Quality Control

Our 4-Ethoxybenzene-1,2-Diamine is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques including HPLC, GC, and NMR for identity confirmation and impurity profiling. Certificates of Analysis (COA) detailing purity, assay, and related substances are provided with each shipment. Our quality commitment aligns with cGMP principles where applicable, supporting its use in regulated synthesis pathways.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its nature as an aromatic diamine that is easily oxidized (store under inert atmosphere) and light-sensitive (store away from light), it is recommended to handle under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize headspace in opened containers. Keep away from strong oxidizing agents.
