Quality Control

Our Potassium 4-Chloro-3,5-Dinitrobenzenesulphonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and impurity profiles. Certificates of Analysis (COA) documenting results from HPLC, IR, and titration methods are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong reducing agents.
