Quality Control

Our 7-[[2-[(Aminocarbonyl)Amino]-4-[(4,6-Dichloro-1,3,5-Triazin-2-Yl)Amino]Phenyl]Azo]Naphthalene-1,3,6-Trisulphonic Acid is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for dye intermediate applications. Certificates of Analysis (COA) detailing purity, impurity profile, and physical data are available upon request to support your quality assurance protocols.

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