Used as an intermediate in the synthesis of organic semiconductors, particularly in the development of conjugated polymers for organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its bromine functionality allows for palladium-catalyzed cross-coupling reactions, enabling the construction of complex π-conjugated systems. It is valued in materials chemistry for enhancing charge carrier mobility and thermal stability in thin-film electronic devices. Also explored in the design of donor-acceptor copolymers for high-performance printable electronics.
