Quality Control

Our production of 4-[[1-[[(2-Chlorophenyl)Amino]Carbonyl]-2-Oxopropyl]Azo]-3-Nitrobenzenesulphonic Acid adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. The material undergoes rigorous analytical testing, including HPLC for assay and impurity profiling, to meet precise customer specifications. Certificates of Analysis (COA) detailing identity, purity, and related substances are provided with each 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 sealed to prevent absorption of atmospheric moisture, which can affect product stability and performance.
