Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its halogenated aromatic structure allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex drug candidates. It is also employed in the preparation of agrochemicals and functional materials where specific substitution patterns on the benzene ring enhance biological activity or material properties. The hydroxyl group enables further functionalization, such as esterification or ether formation, facilitating its incorporation into larger molecular architectures.
