Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its structure allows for selective functionalization in heterocyclic chemistry, making it valuable in the development of active ingredients in crop protection agents and medicinal compounds. It is also employed in research for constructing complex nitrogen-containing molecules through cross-coupling reactions. Due to the presence of the bromine atom, it serves as a good leaving group in palladium-catalyzed reactions such as Suzuki or Buchwald-Hartwig couplings.
