Used as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds and pharmaceuticals. It serves as a derivatizing agent for carbonyl compounds, aiding in the identification and characterization of aldehydes and ketones through hydrazone formation. Also employed in the development of dyes and agrochemicals due to its reactive functional groups. Its bromo and nitro substituents allow for further functionalization via cross-coupling reactions or reduction, making it valuable in multi-step synthetic routes.
