高锰酸钾，Potassium permanganate；ACS reagent, ≥99.0%, low in mercury

Potassium permanganate (PP, KMnO₄) is a dark violet colored crystalline solid. It is a strong oxidizing agent used in the oxidation of a wide range of organic compounds.[1] PP is commonly used as a disinfectant to treat external infections in aquaculture.[2] Corncobs pretreated with alkaline potassium permanganate solution showed high carbohydrate recovery due to the increased enzymatic hydrolysis of lignocellulose.[3] The acidic potassium permanganate chemiluminescence detection has been employed for the detection of cannabinoids.[4]

 

Potassium permanganate was used in the preparation of layered MnO₂ which may be employed as cathodic material in lithium secondary batteries.[5]
It may be used as an oxidant in:

• The reduction of polycyclic aromatic hydrocarbons found in coal tar pitches (CTPs).[6]
• Oxidation of decabromodiphenyl ether in sulfuric acid medium.[7]
• Oxidative cleavage of oximes to the corresponding carbonyl compounds potassium permanganate supported on kieselguhr.[8]
• Oxidation of progestagens.[9]
