Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its halogenated structure allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in Suzuki and Stille coupling reactions to introduce aryl or vinyl groups during drug discovery. Also utilized in agrochemical research for designing novel pesticides due to its reactivity and structural versatility.
