Used in pharmaceutical research as a key intermediate in the synthesis of serotonin receptor modulators. Its structure supports the development of neuroactive compounds, particularly those targeting central nervous system disorders such as depression, anxiety, and migraines. The presence of the indole ring with a fluorine substituent enhances binding selectivity and metabolic stability in resulting drug candidates. Also explored in the design of prodrugs due to the primary alcohol group, which allows for esterification or conjugation to improve bioavailability.
