Quality Control

Our production of Disodium Hydrogen 5-[[4'-[[8-Amino-1-Hydroxy-7-[(4-Nitrophenyl)Azo]-3,6-Disulphonato-2-Naphthyl]Azo][1,1'-Biphenyl]-4-Yl]Azo]Salicylate adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity for industrial applications. The product is manufactured under a quality system and undergoes comprehensive analytical testing, including HPLC for assay and purity, and spectroscopic methods for structural confirmation. A Certificate of Analysis (COA) detailing specific results for identity, purity, and related substances is provided with each shipment.

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 quality and handling properties.
