Quality Control

Our production of 4-[[2-[(4-Chloro-2-Nitrophenyl)Azo]-1,3-Dioxobutyl]Amino]Benzenesulphonic Acid adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and quality assurance for your production processes.

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 such as strong oxidizing agents.
