Quality Control

Our production of Calcium Bis[4-[[1-[[(4-Methylphenyl)Amino]Carbonyl]-2-Oxopropyl]Azo]-3-Nitrobenzenesulphonate] adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and spectrophotometry for color strength, to ensure it meets exacting industry specifications. Certificates of Analysis (COA) documenting all critical parameters are provided with each shipment to guarantee traceability and batch-to-batch consistency for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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.
