Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. It serves as a building block for heterocyclic compounds with potential anticonvulsant, anxiolytic, and muscle relaxant properties. Its structure supports the design of novel bioactive molecules in medicinal chemistry research. Also employed in the preparation of fluorescent probes and dyes due to its electron-withdrawing and rigid aromatic framework, useful in imaging and sensor applications.
