Used in pharmaceutical research as an intermediate for synthesizing bioactive compounds, particularly in the development of central nervous system agents. Shows potential in the study of neurodegenerative diseases due to its structural similarity to known dopamine receptor ligands. Also employed in the preparation of alkaloid derivatives with possible antitumor and anti-inflammatory properties. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies of tetrahydroisoquinoline-based drugs.
