Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Its halogenated indole structure makes it valuable in the development of drugs targeting neurological disorders and cancer. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to build complex indole derivatives. Also utilized in the synthesis of tryptamine and tryptophan analogs, which play roles in medicinal chemistry and neuroscience research. Shows potential in the creation of fluorescent probes due to the indole core’s photophysical properties.
