Potassium permanganate is an inorganic compound with the chemical formula KMnO₄. It is a purplish-black crystalline salt, that dissolves in water as K⁺ and MnO⁻
₄, an intensely pink to purple solution.

Potassium permanganate is widely used in the chemical industry and laboratories as a strong oxidizing agent, and also as a medication for dermatitis, for cleaning wounds, and general disinfection. It is on the World Health Organization's List of Essential Medicines.^[5] In 2000, worldwide production was estimated at 30,000 tons.^[5]
