Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex aromatic frameworks. Also employed in the preparation of agrochemicals and dyes due to its reactivity and substitution pattern. The presence of both amino and hydroxyl groups enables coupling reactions, while halogen atoms facilitate cross-coupling transformations in advanced synthetic routes.
