Used primarily in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds targeting central nervous system disorders. Shows affinity for serotonin and dopamine receptor subtypes, making it valuable in developing potential antipsychotic and antidepressant agents. Also employed in structure-activity relationship (SAR) studies to optimize pharmacokinetic properties of novel piperazine-based therapeutics. Its sulfonamide and fluorophenyl groups enhance metabolic stability and blood-brain barrier penetration, which are advantageous for CNS drug candidates.
