Used primarily in organic synthesis as an intermediate for pharmaceuticals and advanced materials. Serves as a building block in the preparation of conjugated organic compounds for optoelectronic devices such as organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its halogen substituents enable cross-coupling reactions, particularly in palladium-catalyzed processes like Suzuki or Ullmann couplings, allowing the construction of complex aromatic systems. Also employed in the development of nonlinear optical materials due to its extended π-conjugation and electron-rich character.
