Used as a key intermediate in organic synthesis, particularly in the preparation of functional materials for optoelectronic devices. Commonly employed in the development of hole-transport materials for perovskite solar cells due to its excellent charge-transport properties and stability. Also utilized in the synthesis of dyes and photoactive compounds for use in photovoltaics and organic light-emitting diodes (OLEDs). Its derivatization supports cross-coupling reactions, enabling the construction of complex conjugated systems in advanced material science.
