Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of selective receptor modulators. Its bromine and sulfonic acid functional groups allow for selective cross-coupling reactions and sulfonation modifications, making it valuable in building complex heterocyclic systems. Commonly employed in medicinal chemistry for constructing kinase inhibitors and nicotinic acetylcholine receptor ligands. Also utilized in materials science for designing functionalized polymers and catalysts due to its ability to coordinate with metal centers.
