Quality Control

Our production of Trisodium 5-[[4'-[(8-Amino-1-Hydroxy-3,6-Disulphonato-2-Naphthyl)Azo]-3,3'-Dimethoxy[1,1'-Biphenyl]-4-Yl]Azo]Salicylate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometry for color strength, and elemental analysis, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) detailing all test parameters are provided with each shipment.

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 each use to prevent absorption of atmospheric moisture, which can affect product performance and stability.
