Quality Control

Our production of Disodium 2-[1-Ethyl-3-(2-Methyl-4-Nitrophenyl)-2-Triazenyl]-5-Sulphonatobenzoate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR spectroscopy, to ensure consistency and meet precise customer specifications. A Certificate of Analysis (COA) detailing all critical parameters is provided with each shipment to guarantee traceability and compliance.

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 sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
