Quality Control

Our production of Calcium 2-[[2-Hydroxy-3-[[(3-Nitrophenyl)Amino]Carbonyl]-1-Naphthyl]Azo]Naphthalenesulphonate adheres to stringent quality protocols to ensure batch consistency and purity for industrial applications. Each lot undergoes comprehensive analysis, including HPLC for purity, spectrophotometry for color value, and metal content analysis. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

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 degradation from atmospheric moisture. Keep away from incompatible materials.
