Used primarily as an intermediate in organic synthesis, especially in the development of pharmaceuticals and agrochemicals. Its azide and aldehyde functional groups allow participation in click chemistry reactions, such as copper-catalyzed azide-alkyne cycloaddition (CuAAC), enabling efficient construction of triazole-containing compounds. The electron-withdrawing nitro group enhances reactivity in nucleophilic addition and condensation reactions. It is also employed in the synthesis of heterocyclic compounds and fluorescent probes due to its ability to undergo cyclization and derivatization under mild conditions. Its dual functionality makes it valuable in combinatorial chemistry and drug discovery for building molecular complexity.
