Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. It serves as a building block for developing kinase inhibitors and other targeted therapies in oncology. Its halogenated structure allows for further functionalization via cross-coupling reactions like Suzuki or Heck reactions, enabling the creation of diverse compound libraries for drug discovery. Also employed in the development of fluorescent probes due to its rigid aromatic framework, useful in cellular imaging and biochemical assays.
