Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of nicotinic acid derivatives, which show biological activity in medicinal chemistry. Commonly employed in the development of kinase inhibitors and other bioactive molecules due to the presence of reactive bromo and hydroxy functional groups. Also utilized in cross-coupling reactions, such as Suzuki or Heck reactions, to form C–C bonds in heterocyclic compound synthesis. Its ester group allows for further derivatization, making it valuable in drug discovery and the design of new therapeutic agents.
