Used in pharmaceutical research as a key intermediate in the synthesis of serotonin receptor modulators, particularly targeting 5-HT3 and 5-HT6 receptors. It shows potential in developing treatments for neurological disorders such as depression, schizophrenia, and cognitive impairments. Its fluorinated indole structure enhances binding affinity and metabolic stability, making it valuable in optimizing drug candidates for central nervous system activity. Also explored in the development of PET tracers for neuroimaging due to the presence of fluorine-18 labeling potential.
