Used as a key reagent in organic synthesis, particularly in the preparation of aziridines through the aziridination of alkenes. It serves as a source of the nitrene group in metal-catalyzed reactions, enabling the formation of three-membered nitrogen-containing rings which are valuable intermediates in pharmaceutical and agrochemical synthesis. Its stability and reactivity profile make it suitable for selective transformations in complex molecule assembly. Commonly employed in research settings for C–H amination and heterocycle formation.
