Used as a monomer in the synthesis of conjugated polymers for organic electronic devices such as organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its boron-containing heterocyclic structure enables unique electronic properties, enhancing charge transport and stability in semiconductor materials. Also employed in cross-coupling reactions as a boronate ester for the preparation of complex aromatic systems in pharmaceutical and agrochemical intermediates.
