Quality Control

Our Disodium 5-[[4-[[[4-[[2,4-Dihydroxy-5-[[2-Hydroxy-5-[(3-Sulphonatophenyl)Azo]Phenyl]Azo]Phenyl]Azo]Phenyl]Amino]Carbonyl]Phenyl]Azo]Salicylate is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for dye intermediate applications. Certificates of Analysis (COA) documenting batch-specific results are available upon request, providing full traceability and quality assurance for your manufacturing processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in the original packaging or opaque containers until use.
