Used in organic electronics as a building block for semiconductor materials, particularly in the development of organic light-emitting diodes (OLEDs), organic transistors, and organic photovoltaics (OPVs). Its structure supports hole transport, exhibits good electrical conductivity, thermal stability, and light absorption in desired wavelengths, enhancing device efficiency. Also employed in the synthesis of dyes and fluorescent probes for sensing applications, including light sensors. Serves as an intermediate in pharmaceuticals and agrochemicals due to its reactive chlorine group enabling further functionalization.
