Used as an intermediate in the synthesis of functional organic materials, particularly in the development of conjugated polymers and small-molecule semiconductors for organic electronics. Its structure allows for further functionalization via cross-coupling reactions, making it valuable in creating fluorescent dyes and optoelectronic materials. Commonly employed in the preparation of hole-transport materials and emissive layers in OLEDs. Also serves as a building block in medicinal chemistry for constructing nitrogen-containing heterocycles through nitro group transformations.
