Used primarily as a precursor for the on-site generation of chlorine dioxide, a potent disinfectant in water treatment systems. Effective in controlling microbial growth, including bacteria, viruses, and spores, in drinking water, wastewater, industrial process water, and for odor control, while producing minimal harmful byproducts.

In the pulp and paper industry, applied for bleaching cellulose and removing lignin, particularly in elemental chlorine-free (ECF) processes.

Utilized in antimicrobial solutions for food processing equipment, surfaces, and washing vegetables and fruits due to its efficacy against microorganisms.

Found in specialized cleaning products, surface disinfectants, and odor control systems.

Occasionally serves as an intermediate in the production of other chemicals, such as bleaching agents or in organic synthesis.

Limited use in small-scale applications for mouthwash or dental hygiene products due to safety concerns.
