Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for constructing indole-based drug candidates. It is also employed in the preparation of fluorinated analogs in drug discovery programs to enhance metabolic stability and bioavailability. Additionally, it serves as a building block in the creation of biologically active molecules targeting neurological disorders and inflammation.
