Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nitrogen-containing heterocyclic compounds with potential biological activity. It serves as a building block in medicinal chemistry for creating kinase inhibitors and antimicrobial agents. Its bromine functionality allows for cross-coupling reactions, enabling the introduction of various substituents to tailor molecular properties. Also employed in the preparation of fluorescent dyes and optoelectronic materials due to the extended aromatic system.
