Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents. It serves as a building block for receptor ligands targeting serotonin and dopamine pathways, making it valuable in the discovery of new treatments for neurological and psychiatric disorders. Its structural flexibility allows for modification to enhance selectivity and binding affinity in drug candidates. Also employed in the preparation of novel piperazine-based derivatives for structure-activity relationship studies.
