Used in pharmaceutical research as a key intermediate for developing central nervous system (CNS) active compounds, particularly in the synthesis of selective receptor antagonists or modulators targeting neurological disorders. Shows potential in the development of treatments for schizophrenia, depression, and other psychiatric conditions due to its structural affinity for dopamine and serotonin receptors. Also explored for its role in improving cognitive function and behavioral regulation in preclinical studies. Its chloroquinoline core enhances binding specificity, while the hydroxypiperidine moiety contributes to blood-brain barrier permeability, making it valuable in designing brain-penetrant therapeutics.
