Quality Control

Our Disodium 5-(Benzoylamino)-3-[[2-[2-(tert-Butyl)-5-Methylphenoxy]Phenyl]Azo]-4-Hydroxynaphthalene-2,7-Disulphonate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including HPLC for assay and impurity profiling. Certificates of Analysis (COA) detailing identity, purity, and related substance data are provided with every 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 after each use to prevent moisture absorption and degradation.
