Quality Control

Our 4,4′-Diaminodiphenylamine Sulfate Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards and consistent performance for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

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 to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
