Quality Control

Our Sodium 2-Chloro-5-Nitrobenzenesulphinate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

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 nature, the container must be kept tightly sealed to prevent moisture absorption. Keep away from incompatible materials such as strong oxidizing agents.
