Potassium permanganate is an inorganic chemical compound and medication. As a medication it is used for cleaning wounds and dermatitis.[5]  

It has the chemical formula KMnO4 and is a salt consisting of K+ and MnO−

4 ions. It is a strong oxidizing agent. It dissolves in water to give intensely pink or purple solutions, the evaporation of which leaves prismatic purplish-black glistening crystals.[6] In 2000, worldwide production was estimated at 30,000 tonnes.[7] In this compound, manganese is in the +7 oxidation state.
