It is widely used as a disinfectant, water treatment chemical, oxidizing agent in organic synthesis, and in medicine for antiseptic purposes. It is effective in removing iron, manganese, and hydrogen sulfide from water and controlling odors and tastes. Due to its strong oxidative nature, it is handled with care to prevent unwanted reactions.
