Quality Control

Our Disodium 2-[3-(4-Chloro-2-Tolyl)-1-Methyltriazen-2-Yl]-5-[[Methyl(2-Sulphonatoethyl)Amino]Sulphonyl]Benzoate is manufactured under a strict 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 provided with each shipment to guarantee batch-to-batch consistency and reliability for your synthesis processes.

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.
