Quality Control

Our Sodium 4-Chloro-5-Nitrotoluene-3-Sulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC and titration methods, to ensure it meets precise purity and compositional specifications. A Certificate of Analysis (COA) detailing all relevant parameters is provided with each shipment to guarantee traceability and compliance.

Storage

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