Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for creating analogs in drug discovery programs. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to build complex heterocyclic systems. Also utilized in agrochemical research for designing new active ingredients in crop protection agents. Its bromine moiety serves as a good leaving group, facilitating rapid derivatization in combinatorial chemistry and high-throughput screening libraries.
