Used as a catalyst in organic synthesis, particularly in oxidation reactions and polymerization processes. It serves as a precursor for preparing manganese-based nanomaterials and thin films in material science. Employed in the formulation of fuel additives to enhance combustion efficiency and reduce engine knock. Applied in research as a paramagnetic reagent for spectroscopic studies and magnetic materials development. Also utilized in the production of specialty coatings and ceramics requiring manganese doping.
