Used in the synthesis of bioactive molecules, particularly in pharmaceutical research for developing compounds with potential neurological and cardiovascular effects. It serves as a key intermediate in creating isoquinoline-based alkaloids, which are known for their antimicrobial, anti-inflammatory, and antitumor properties. Also employed in the design of selective enzyme inhibitors and receptor ligands for central nervous system disorders. Its structure supports derivatization for drug discovery and optimization in medicinal chemistry.
