Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting central nervous system disorders. Its structure supports modification for enhancing binding affinity to certain receptors, making it valuable in medicinal chemistry research. Also employed in the preparation of sulfonamide-based derivatives with potential antimicrobial or anti-inflammatory properties. Commonly utilized in laboratory settings for structure-activity relationship studies due to its stable piperazine core and reactive sulfonyl group.
