Quality Control

Our Sodium 4-Chloro-3-[4-[[2-[(2-Chlorophenoxy)Sulphonyl]Phenyl]Azo]-2,5-Dihydro-5-Imino-3-Methyl-1H-Pyrazol-1-Yl]Benzenesulphonate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for industrial applications. Each lot is analyzed using advanced techniques like HPLC and spectrophotometry to confirm identity, strength, and impurity profiles. Certificates of Analysis (COA) documenting all critical specifications are provided with every shipment to support your quality assurance processes.

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 after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
