Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of quinoline-based drugs. Its structure supports the creation of bioactive molecules with potential antimicrobial, antiviral, and anticancer properties. The bromo and methoxy functional groups allow for further chemical modifications through cross-coupling reactions, making it valuable in medicinal chemistry research. It is also employed in the preparation of fluorescent probes and dyes due to the inherent photophysical properties of the quinoline scaffold.
