Used as a key intermediate in the synthesis of pharmaceuticals and biologically active compounds, particularly in the development of kinase inhibitors and antitumor agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to form C–C bonds in drug discovery pipelines. Also utilized in the preparation of pyrrole-based natural product analogs and functional materials.
