Used as an intermediate in organic synthesis, particularly in the preparation of conjugated materials for optoelectronic devices such as organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its extended π-conjugated structure enhances electron delocalization, making it valuable in the development of organic semiconductors. Also employed in cross-coupling reactions to build complex aromatic and acetylenic frameworks found in pharmaceuticals and functional materials.
