Quality Control

Our 4-Nitrobenzene-1,2-Diammonium Sulphate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity, consistent composition, and batch-to-batch reliability. Standard testing includes assay, identification, and impurity profiling. Certificates of Analysis (COA) detailing all specifications and test results are available upon request to support your quality assurance protocols.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and handling properties. Keep away from incompatible materials such as strong oxidizing agents.
