Quality Control

Our Disodium 3-(Acetylamino)-8-Hydroxynaphthalene-1,5-Disulphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for use as a dye intermediate. Certificates of Analysis (COA) documenting batch-specific results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is light-sensitive (store away from light) and hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed to prevent moisture absorption and degradation.
