Quality Control

Our production of Disodium 7-Amino-3-[[2,5-Dimethyl-4-[(2-Methyl-4-Sulphonatophenyl)Azo]Phenyl]Azo]-4-Hydroxynaphthalene-2-Sulphonate adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. The material undergoes rigorous analytical testing, including HPLC for assay and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and other critical parameters is provided with each shipment to support your quality assurance requirements.

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 after opening to prevent absorption of atmospheric moisture, which can affect product performance.
