Quality Control

Our production of Tetrasodium 2-[[5-(Aminocarbonyl)-1,6-Dihydro-4-Methyl-2-Oxido-6-Oxo-1-[2-(4-Sulphonatophenyl)Ethyl]-3-Pyridyl]Azo]-5-[(3-Phosphonatophenyl)Azo]Benzenesulphonate adheres to a stringent quality management system to ensure batch-to-batch consistency and purity for industrial synthesis. Every lot undergoes comprehensive analytical testing, including HPLC for purity and isomer content, spectrophotometry for color strength, and elemental analysis. A detailed Certificate of Analysis (COA) documenting identity, assay, impurity profile, and physical properties is provided with each shipment 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product stability and handling properties. Keep away from incompatible materials.
