Used in pharmaceutical research as an intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents. Shows potential in the study of serotonin and dopamine receptor modulators due to the piperazine and heteroaromatic scaffold. Also employed in the preparation of novel derivatives for screening in neuropharmacology and psychiatric disorder treatments. Its benzo[b]thiophene core contributes to enhanced lipophilicity and binding affinity in receptor assays.
