Used as a key reagent in organic synthesis, particularly in the preparation of heterocyclic compounds and pharmaceutical intermediates. It serves as a diazo transfer agent, enabling the introduction of diazo groups into various substrates, which is valuable in the synthesis of complex molecules such as antibiotics and antiviral agents. Its reactivity also makes it useful in cycloaddition reactions and the development of agrochemicals. Due to its ability to form nitrogen-rich structures, it is employed in the research of energetic materials and functional dyes.
