Product name: Potassium permanganate Level: AR / CP
Implementation of the standards: GB / T 643-2008
Molecular formula: KMnO4
Properties: This reagent is dark purple metallic luster crystals dissolve in water, ethanol and other organic solvents in case it is reduced to lower manganese compound.
Hazardous characteristics: strong oxidants. In case of sulfuric acid, hydrogen peroxide, ammonium or explosion. In case of glycerol, ethanol can cause spontaneous combustion. With organic, reductant, combustibles such as combustion caused a risk of explosion in contact or mixed sulfur, phosphorus and other.
Incompatible products: Strong reducing agents, active metal powder, sulfur, aluminum, zinc, copper and its alloys, flammable or combustible materials.
