Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of receptor antagonists and kinase inhibitors. Its structure allows for selective modification, making it valuable in creating bioactive molecules for treating inflammatory diseases and certain cancers. Commonly employed in medicinal chemistry for constructing complex heterocyclic systems due to its reactive halogen sites, which support cross-coupling reactions like Suzuki and Heck reactions. Also utilized in the preparation of agrochemicals and functional materials where aromatic heterocycles are required.
