Used as a key intermediate in the synthesis of organic electronic materials, particularly for organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its boronic acid group enables efficient cross-coupling reactions, such as Suzuki-Miyaura coupling, to create conjugated polymers or small molecules with tailored optoelectronic properties. Also employed in the development of sensors and molecular probes due to its ability to bind selectively with diols or other target molecules. Its thiophene moiety contributes to enhancing charge transport properties in semiconductor applications.
