Quality Control

Our 4-(Methyl)Benzenediazoniumsulphate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling, to ensure it meets the high standards required for industrial and research applications. A Certificate of Analysis (COA) detailing purity, identity, and other critical parameters is provided with every shipment to guarantee traceability and consistency.

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 tightly sealed to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and incompatible materials.
