Used primarily as an intermediate in organic synthesis, especially in the pharmaceutical and agrochemical industries. It serves as a building block for the preparation of bioactive molecules due to the presence of both bromine and indole functionalities, which are amenable to cross-coupling reactions such as Suzuki or Heck reactions. Commonly employed in the development of serotonin receptor ligands and other neuroactive compounds. Also utilized in the synthesis of functional materials and fluorescent probes, where the indole core contributes to electronic properties. Its methyl and bromo substituents allow selective modifications, making it valuable in medicinal chemistry for structure-activity relationship studies.
