Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure allows for functionalization in cross-coupling reactions, making it valuable in the development of bioactive molecules. Commonly employed in the synthesis of fluorescent dyes and optical brighteners due to its heterocyclic core. Also finds use in materials science for designing electron-transport materials in OLEDs. Its bromine moiety facilitates metal-catalyzed reactions like Suzuki or Heck couplings, enabling the construction of complex aromatic systems.
