Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and biologically active compounds. It plays a role in oxidation reactions where it acts as a mild oxidizing agent. Commonly employed in the synthesis of pyridine derivatives and nitrogen-containing heterocycles, which are important in drug development. Also utilized in research settings for modifying alkaloids and other nitrogenous structures to enhance solubility or alter biological activity. Its ability to participate in N-oxide-directed C–H functionalization makes it valuable in modern synthetic methodologies for building complex molecules.
