Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Its iodine substituent allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex indole derivatives. Commonly employed in the development of medicinal agents, including potential kinase inhibitors and central nervous system modulators. Also utilized in research for labeling and tracer studies due to the presence of iodine, which can be substituted with radioactive isotopes for imaging or therapeutic applications.
