Quality Control

Our production of Tetrasodium 4-[[4-Chloro-6-[[8-Hydroxy-3,6-Disulphonato-7-[(1-Sulphonato-2-Naphthyl)Azo]-1-Naphthyl]Amino]-1,3,5-Triazin-2-Yl]Amino]Salicylate adheres to stringent quality management systems. Every batch undergoes rigorous analytical testing to ensure consistent purity, color strength, and performance. Certificates of Analysis (COA) documenting key specifications 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 (moisture-sensitive) nature, the container must be kept tightly sealed after use to prevent absorption of atmospheric moisture, which can affect product performance.
