Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial, antimicrobial, antiviral, and anticancer agents. Its structure, featuring bromo and nitro groups, allows for selective functionalization through reactions such as nucleophilic substitution or condensation with other compounds, making it valuable in medicinal chemistry for building complex quinoline-based molecules. It also serves in research settings to develop novel bioactive compounds and fluorescent probes due to its electron-withdrawing substituents that influence photophysical properties. Additionally, it functions as a reagent in bromine group transfer reactions or as a ligand in transition metal complexes to facilitate catalytic processes.
