Quality Control

Our 2-[[8-[[4-[Bis[2-[(2-Chloroethyl)Sulphonyl]Ethyl]Amino]-6-Chloro-1,3,5-Triazin-2-Yl]Amino]-1-Hydroxy-3,6-Disulpho-2-Naphthyl]Azo]Naphthalene-1,5-Disulphonic Acid is produced under strict quality management protocols. Every 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) documenting purity, impurity profile, and physical characteristics are available upon request to support your quality assurance and regulatory needs.

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