Quality Control

Our production of Sodium 2-[[5-Carbamoyl-1-Ethyl-1,6-Dihydro-2-Hydroxy-4-Methyl-6-Oxo-3-Pyridyl]Azo]-4-[(2,3-Dibromo-1-Oxopropyl)Amino]Benzenesulphonate adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance as a dye intermediate. Certificates of Analysis (COA) detailing specific batch results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
