Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of indole-based derivatives with potential biological activity. It serves as a building block in medicinal chemistry for creating analogs that may exhibit anti-inflammatory, antimicrobial, or central nervous system-modulating effects. Its functional groups allow for further chemical modifications, making it valuable in the design of new drug candidates. Also employed in research settings to explore structure-activity relationships in heterocyclic compounds.
