Used in organic synthesis as a diazo intermediate for constructing nitrogen-containing heterocycles. Its reactivity allows for cycloaddition and insertion reactions, making it valuable in pharmaceutical research for developing bioactive molecules. It serves as a precursor in the preparation of imidazole-based compounds with potential antimicrobial and antiviral properties. Also employed in photochemical studies due to its light-sensitive diazo group, enabling controlled release or activation in specialized materials.
