Quality Control

Our production of Trisodium 8-[[4-Methyl-3-[(3-Nitrobenzoyl)Amino]Benzoyl]Amino]Naphthalene-1,3,5-Trisulphonate adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay (HPLC), sulfonate content, moisture, and heavy metal limits. Our quality system is designed to meet the demanding specifications of the dye and fine chemical industries.

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 nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product quality and handling properties. Keep away from incompatible materials.
