Used in organic synthesis as an intermediate for pharmaceuticals and optoelectronic materials. Serves as a building block in the preparation of fluorescent dyes and conjugated polymers due to its rigid aromatic structure. Commonly employed in cross-coupling reactions, such as Suzuki and Heck reactions, to construct complex organic frameworks. Also utilized in the development of organic semiconductors and ligands for metal complexes in catalysis. Its bromo functional group allows for easy modification, making it valuable in medicinal chemistry for structure-activity relationship studies.
