Quality Control

Our trisodium azo dye intermediate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including HPLC for assay and impurity profile, to meet exacting customer specifications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and physical parameters is provided with every shipment to support your quality assurance processes.

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