Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure supports the formation of bioactive molecules by serving as a building block in heterocyclic chemistry. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the bromine atom, which allows further functionalization via cross-coupling reactions like Suzuki or Heck reactions. Also utilized in the preparation of ligands for metal-catalyzed reactions and in the design of kinase inhibitors. Its stability and reactivity make it suitable for use in solid-phase and combinatorial synthesis.
