Quality Control

Our production of Sodium 3-[[2-Hydroxy-3-[(2-Methoxyphenyl)Carbamoyl]-1-Naphthyl]Azo]Benzenesulphonate adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. The material is manufactured and tested in facilities that follow cGMP principles where applicable. Comprehensive quality testing, including identity confirmation, purity assay, and impurity profiling, is performed. A Certificate of Analysis (COA) detailing all test results and specifications is provided with each shipment to guarantee 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). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be opaque or stored in darkness to prevent degradation. Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture.
