Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds, particularly in the development of indole-based drugs. Commonly employed in the preparation of serotonin receptor modulators and kinase inhibitors due to the indole scaffold’s prevalence in medicinal chemistry. Also utilized in research settings for the synthesis of fluorescent probes and labeled compounds for biochemical assays. Its bromo functional group allows for further derivatization via cross-coupling reactions such as Suzuki or Heck reactions, making it valuable in building complex molecular architectures.
