Quality Control

Our 3-[[2-[(3-Chlorophenyl)Amino]-1-Naphthyl]Azo]-4-Hydroxybenzenesulphonamide is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling. Certificates of Analysis (COA) detailing purity, identity, and other critical 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 a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be opaque or stored in dark conditions to prevent degradation.
