Quality Control

Our n-Methyl-1,4-Phenylenediamine Dihydrochloride is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, IR for identification, and loss on drying for moisture content, to ensure it meets exacting specifications. A Certificate of Analysis (COA) is provided with each shipment, guaranteeing traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
