Used as a key intermediate in the synthesis of pharmaceuticals and biologically active compounds, particularly in the development of serotonin receptor modulators and other central nervous system agents. Its halogenated indole structure makes it valuable in medicinal chemistry for constructing complex heterocyclic systems. It is also employed in research settings to prepare fluorescent probes and imaging agents due to the reactivity of the indole core and the directing effects of the bromo and chloro substituents. Commonly utilized in cross-coupling reactions such as Suzuki or Buchwald-Hartwig to build more complex molecules in drug discovery programs.
