Used as a key intermediate in organic synthesis, particularly in the preparation of conjugated materials for electronic applications. It serves as a building block in the synthesis of organic semiconductors and liquid crystals due to its ability to undergo cross-coupling reactions, such as Suzuki or Heck couplings, enabling the construction of extended π-systems. Its vinyl bromide functionality allows for selective functionalization, making it valuable in the development of optoelectronic devices like OLEDs and organic photovoltaics. Also employed in the synthesis of pharmaceuticals and agrochemicals where aromatic-vinyl frameworks are required.
