Used in pharmaceutical synthesis as a key intermediate for alkaloid-based drugs, particularly in the development of central nervous system agents. It serves as a building block for compounds with analgesic, antihypertensive, and neuroactive properties. Commonly employed in the preparation of tetrahydroisoquinoline derivatives that exhibit dopamine or serotonin receptor activity. Also utilized in research related to Parkinson’s disease and other neurological disorders due to its structural similarity to endogenous neurotransmitters. Its amine functionality allows for easy modification in medicinal chemistry campaigns aimed at optimizing bioavailability and receptor selectivity.
