Quality Control

Our production of 4,4'-[(3,3'-Dimethoxy[1,1'-Biphenyl]-4,4'-Diyl)Bis(Azo)]Bis[2,4-Dihydro-5-Methyl-2-Phenyl-3H-Pyrazol-3-One] adheres to stringent quality management systems. Every batch undergoes rigorous analytical testing including HPLC for purity, spectrophotometry for color strength, and residue analysis to ensure it meets precise customer and industry specifications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and physical parameters is provided with each shipment to guarantee traceability and compliance.

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). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature (store away from light), prolonged exposure to direct light should be avoided to maintain product integrity.
