Quality Control

Our production of Disodium 4-[[4,5-Dihydro-3-Methyl-5-Oxo-1-(4-Sulphonatophenyl)-1H-Pyrazol-4-Yl]Azo]-4'-[(2,5,6-Trichloropyrimidin-4-Yl)Amino][1,1'-Biphenyl]-3-Sulphonate adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

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, which can affect product quality.
