Quality Control

Our production of 5-[[4-Chloro-6-[Methyl(Phenyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-4-Hydroxy-3-[(2-Sulfophenyl)Azo]-2,7-Naphthalenedisulfonic Acid 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 specifications for dye intermediate applications. Certificates of Analysis (COA) detailing batch-specific results are provided to guarantee traceability and consistency for our industrial partners.

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 when not in use to prevent absorption of atmospheric moisture. Keep away from strong acids and organic solvents.
