Used in pharmaceutical research as a key intermediate in the synthesis of selective receptor modulators, particularly targeting neurological pathways. Shows relevance in developing compounds with potential antidepressant and anxiolytic activity. Also employed in the study of dopamine and serotonin receptor interactions due to its structural affinity for these targets. Its derivatives are explored for central nervous system disorders, including cognitive and mood-related conditions. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving piperazine-based bioactive molecules.
