Used in organic synthesis as a versatile intermediate for constructing complex molecules, particularly in pharmaceutical research. It serves as a building block for developing quinoline-based compounds, which are explored for their potential biological activities, such as antimicrobial, anticancer, and anti-inflammatory properties. Additionally, it is employed in the preparation of fluorescent dyes and sensors due to its quinoline core, which can be modified to enhance optical properties. Its bromomethyl group allows for further functionalization, making it valuable in creating targeted chemical probes and ligands for biochemical studies.
