Used in organic synthesis as an intermediate for pharmaceuticals, particularly in the development of alkaloid-based drugs. Serves as a building block in the preparation of bioactive molecules with potential neurological and cardiovascular effects. Employed in research settings for the synthesis of tetrahydroisoquinoline derivatives, which are studied for their receptor-binding properties and therapeutic potential in treating central nervous system disorders. Also utilized in medicinal chemistry for structure-activity relationship studies due to its rigid heterocyclic framework.
