Quality Control

Our Disodium 7-[(4-Chloro-6-Methoxy-1,3,5-Triazin-2-Yl)Methylamino]-4-Hydroxy-3-[(4-Methoxy-2-Sulphonatophenyl)Azo]Naphthalene-2-Sulphonate is produced under a stringent quality management system. 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 protocols.

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). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
