Used primarily as an intermediate in organic synthesis, especially in the production of conjugated polymers for organic electronics such as organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its brominated structure allows for palladium-catalyzed cross-coupling reactions, enabling the construction of complex conjugated systems. The presence of methyl groups enhances solubility and influences molecular packing, which can improve charge carrier mobility in semiconductor materials. It is also employed in the synthesis of functionalized thiophene-based small molecules for optoelectronic applications and sensor development.
