Quality Control

Our production of Disodium 5-[[4-[[[[4-[(4-Chloro-3-Sulphonatophenyl)Azo]-2-Ethoxy-5-Tolyl]Amino]Carbonyl]Amino]Phenyl]Azo]Salicylate adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation and spectrophotometry for color value, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) detailing all critical parameters are provided with each shipment to guarantee traceability and consistency.

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 after opening to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from incompatible materials.
