  • Applications

    Sodium dichloroisocyanurate dihydrate (CAS 51580-86-0) is a chlorine-releasing disinfectant used across multiple industries: as a surface sanitizer in household and commercial cleaning products; for water disinfection, including drinking water, swimming pools and spa circuits, and for industrial process water treatment to control microbial growth; for sanitation of equipment and facilities in food processing; for biofilm and algae control in cooling towers and other industrial water systems; and as a biocide in the pulp and paper industry and related process-water systems.
