Quality Control

Our N,n-Diethyl-1,4-Phenylenediamine Dihydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and melting point determination, to ensure it meets exacting standards for industrial and laboratory use. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
