Used as a key intermediate in organic synthesis, particularly in the preparation of conjugated polymers and functionalized aromatic compounds. Its vinyl group enables polymerization reactions, while the bromine atoms allow for further functionalization via cross-coupling reactions such as Suzuki or Heck couplings. Commonly employed in the development of optoelectronic materials, including organic light-emitting diodes (OLEDs) and semiconducting materials. Also utilized in the synthesis of specialty resins and as a building block in pharmaceutical and agrochemical research due to its reactive sites and structural versatility.
