Quality Control

Our production of Barium Bis[2-Chloro-6-[(2-Hydroxy-1-Naphthyl)Azo]Toluene-4-Sulphonate] adheres to stringent quality management systems to ensure batch-to-batch consistency and performance. The material is characterized and tested against rigorous internal specifications for color value, purity, and heavy metal content. A comprehensive Certificate of Analysis (COA) detailing assay, identification, and impurity profiles 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 nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials.
