Application




Potassium permanganate is an oxidizing agent, is used in the synthesis of organic compounds like ascorbic acid, chloramphenicol, saccharin, isonicotinic acid and pyrazinoic acid and in pharmaceutical intermediate. It is used to remove ferrous impurities from inorganic chemicals. It is also used in analytical chemistry as a reagent for redox titrations and to determine the kappa number of wood pulp. It is mostly used in water treatment and as a disinfectant. It also shows useful application as a chemiluminescence reagent.
