Used in pharmaceutical research as an intermediate in the synthesis of bioactive molecules, particularly in the development of central nervous system agents. Shows relevance in the creation of compounds with potential antipsychotic or antidepressant activity due to its structural features involving piperazine and amide moieties. Also employed in medicinal chemistry for structure-activity relationship (SAR) studies, helping optimize drug candidates for improved metabolic stability and receptor binding. Its oxalate salt form enhances crystallinity and purity, beneficial for isolation and characterization during drug development.
