Used primarily as an intermediate in organic synthesis, particularly in the preparation of polycyclic aromatic compounds for materials science applications. It serves as a building block in the development of organic semiconductors and liquid crystalline materials due to its rigid, planar structure. Also employed in the synthesis of advanced dyes and fluorescent probes, where its chlorinated functionality allows for further chemical modification through cross-coupling reactions. Its aromatic framework contributes to thermal stability, making it suitable for high-performance optoelectronic devices.
