Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of indole-based drugs targeting neurological and inflammatory conditions. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for creating analogs with enhanced biological activity. Commonly employed in cross-coupling reactions to form C–C bonds, enabling the construction of complex heterocyclic systems found in bioactive molecules. Also utilized in research settings to develop potential anticancer and antimicrobial agents due to the indole scaffold’s prevalence in natural products with therapeutic properties.
