Used in pharmaceutical research as an intermediate for synthesizing bioactive molecules, particularly in the development of central nervous system agents. Shows relevance in the preparation of compounds with potential antipsychotic or antidepressant activity due to the isoquinoline and piperazine structural motifs. Also employed in medicinal chemistry for structure-activity relationship studies, helping optimize drug candidates targeting neurological disorders. Its tert-butyl carbamate (Boc) group allows for selective protection during multi-step synthesis, making it valuable in peptide and heterocyclic chemistry.
