Quality Control

Our Sodium 2-[(4,5-Dihydro-3-Methyl-5-Oxo-1-Phenyl-1H-Pyrazol-4-Yl)Azo]Benzoate is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
