  • Applications

    Sodium Chlorite (CAS 7758-19-2) is used primarily as an oxidizing agent and disinfectant in industrial water treatment and cooling systems, where it provides oxidative capacity and, via generation of chlorine dioxide, effective biocidal action. In the pulp and paper sector it serves as a chlorine dioxide source for bleaching. In the textile sector it is used for bleaching and color treatment of fabrics to improve brightness and uniformity. In industrial cleaning and surface sanitation, it is incorporated into cleaning formulations to remove contaminants and microbial load, often through chlorine dioxide generation. In chemical manufacturing it functions as an oxidant and as an intermediate in the synthesis of certain oxidative specialty chemicals.
