Quality Control

Our production of Trisodium 5-[[4-[(5-Chloro-2,6-Difluoro-4-Pyrimidinyl)Amino]Benzoyl]Amino]-4-Hydroxy-3-[(2-Sulphonatophenyl)Azo]Naphthalene-2,7-Disulphonate adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and assay, IR for structural identification, and atomic absorption for heavy metal screening, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are provided as standard, guaranteeing traceability, consistency, and compliance with relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled 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.
