Used in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules, particularly in the development of central nervous system agents. It serves as a structural scaffold for compounds with potential antipsychotic, antidepressant, or anxiolytic activity due to its resemblance to known neuroactive piperazine derivatives. Its chlorophenyl group enhances lipophilicity, aiding blood-brain barrier penetration, making it valuable in designing CNS-targeted drugs. Also explored in medicinal chemistry for structure-activity relationship (SAR) studies to optimize receptor binding, especially at serotonin and dopamine receptors.
