Quality Control

Our Trisodium n-[4-[[2-[4-[[1-Amino-8-Hydroxy-7-(Phenylazo)-3,6-Disulpho-2-Naphthyl]Azo]Phenyl]-1H-Benzimidazol-5-Yl]Azo]-3-Hydroxyphenyl]Glycinate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometry for color strength, and tests for residual solvents and heavy metals. A Certificate of Analysis (COA) detailing all specifications is provided to ensure traceability and compliance with your technical requirements.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product performance and stability.
