Used primarily as a pharmaceutical intermediate in the synthesis of active drug substances, particularly in central nervous system agents. Its structure supports modulation of neurotransmitter activity, making it valuable in developing antidepressants and antipsychotics. The compound's lipophilic aromatic groups enhance blood-brain barrier penetration, which is critical for CNS drug efficacy. It is also employed in research settings to explore structure-activity relationships in phenylalkylamine derivatives.
