Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of agrochemicals and active pharmaceutical ingredients (APIs). Its structure allows for selective functionalization, making it valuable in creating herbicides and insecticides. It is also employed in the preparation of kinase inhibitors and other biologically active compounds in medicinal chemistry research. The presence of multiple reactive sites (amino, bromo, chloro groups) enables sequential coupling and substitution reactions, which are essential in building complex heterocyclic systems for drug discovery.
