Used as a key intermediate in organic synthesis, particularly in the production of conjugated polymers for organic electronics such as organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its vinyl-terminated side chain enables further functionalization via cross-coupling reactions or polymerization, making it valuable in constructing pi-conjugated systems. Also employed in the development of specialty monomers for copolymerization processes aimed at tuning the electronic and optical properties of materials. Its thiophene core contributes to electron-rich character, enhancing charge transport in semiconductor materials.
