Used in pharmaceutical research as an intermediate for synthesizing bioactive molecules, particularly in the development of indole-based compounds with potential antitumor, anti-inflammatory, and antimicrobial properties. Its structure serves as a building block in medicinal chemistry for modifying core indole scaffolds to enhance biological activity and selectivity. Also employed in the synthesis of serotonin receptor modulators and kinase inhibitors due to the indole framework's prevalence in neuroactive and signaling molecules.
