Used as a powerful oxidizing agent in organic synthesis, particularly for the selective oxidation of primary alcohols to aldehydes and secondary alcohols to ketones without over-oxidation. It is also employed in the conversion of sulfides to sulfoxides. Additionally, it finds application in the preparation of various heterocyclic compounds and in the synthesis of complex natural products. Its mild reaction conditions and high selectivity make it a valuable reagent in the development of pharmaceuticals and fine chemicals.
