Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) active agents. Its structure supports the creation of compounds with potential antipsychotic, antidepressant, or analgesic properties. The fluorinated tetrahydroisoquinoline core enhances metabolic stability and blood-brain barrier penetration, making it valuable in medicinal chemistry for optimizing drug candidates. Commonly employed in research settings for structure-activity relationship (SAR) studies and the design of novel bioactive molecules.
