Used in pharmaceutical research as a key intermediate in the synthesis of centrally acting agents, particularly those targeting neurological pathways. Its structure supports development of compounds with potential antidepressant, anxiolytic, or cognitive-enhancing effects. The chloro-phenylsulfanyl moiety enhances blood-brain barrier penetration, making it valuable in designing neuroactive drugs. Also employed in structure-activity relationship (SAR) studies to optimize receptor binding, especially for serotonin and dopamine receptors. Limited use outside research due to lack of approved therapeutic products containing this exact scaffold.
