Quality Control

Our production of 5-[[4-[(5-Chloro-2,6-Difluoropyrimidin-4-Yl)Amino]Benzoyl]Amino]-4-Hydroxy-3-[(2-Sulphophenyl)Azo]Naphthalene-2,7-Disulphonic Acid, Sodium Salt adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and consistent batch-to-batch performance. Certificates of Analysis (COA) documenting all critical parameters are provided as standard.

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