Used in pharmaceutical research as an intermediate for synthesizing selective serotonin reuptake inhibitors (SSRIs) and other central nervous system active compounds. Its structure supports binding affinity to serotonin and dopamine receptors, making it valuable in developing antidepressants and antipsychotic drugs. Also employed in studies exploring norepinephrine modulation due to its naphthalene and quinoline moieties, which enhance blood-brain barrier penetration. Commonly used in structure-activity relationship (SAR) studies to optimize potency and reduce off-target effects in neuropsychiatric drug candidates.
