This compound is primarily used in organic synthesis, particularly in the field of polymer chemistry. It serves as a key intermediate in the production of conjugated polymers, which are essential for developing organic electronic devices such as organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and organic field-effect transistors (OFETs). Its role in Stille coupling reactions enables the formation of carbon-carbon bonds, facilitating the synthesis of complex organic molecules with tailored electronic properties. Additionally, it is employed in research to explore new materials for flexible and lightweight electronic applications.
