Quality Control

Our production of Calcium Bis[6-Chloro-4-[(2-Hydroxy-1-Naphthyl)Azo]Toluene-3-Sulphonate] adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity. Each lot is analyzed against comprehensive specifications, including identity, assay, and impurity profiles. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance processes.

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.
