Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki or Negishi couplings to introduce aryl or alkyl groups, enabling the creation of diverse compound libraries for drug discovery. Also utilized in the preparation of ligands for catalysis and in materials science for designing organic semiconductors.
