Used as an oxidizing agent in organic synthesis, particularly for the oxidation of alcohols, sulfides, and alkenes. It is effective in facilitating selective reactions under mild conditions, making it valuable in the preparation of fine chemicals and pharmaceuticals. Commonly employed in the synthesis of heterocycles and for the activation of C–H bonds. Its utility in metal-free oxidation processes makes it a preferred choice in environmentally focused chemistry. Also used in the generation of reactive intermediates such as nitrenes and carbenes for further functionalization reactions.
