Quality Control

Our Barium Bis[5-Chloro-2-[(4,5-Dihydro-3-Methyl-5-Oxo-1-Phenyl-1H-Pyrazol-4-Yl)Azo]-p-Toluenesulphonate] is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, color strength, and chemical composition. Certificates of Analysis (COA) detailing key parameters such as assay, heavy metal content, and specific impurity profiles are available upon request 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 performance.
