Quality Control

Our Tetrasodium 2-[[4-[[4-[(4-Amino-6-Chloro-1,3,5-Triazin-2-Yl)Amino]-6-Sulphonato-1-Naphthyl]Azo]-7-Sulphonato-1-Naphthyl]Azo]Benzene-1,4-Disulphonate is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise industry specifications for dye intermediates. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical parameters is provided with each shipment to guarantee batch-to-batch consistency and performance.

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 to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
