Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. Its structure supports the creation of bioactive molecules with potential applications in treating neurological disorders. Commonly utilized in medicinal chemistry research for constructing isoquinoline-based drug candidates. Also employed in the preparation of selective receptor modulators due to its ability to interact with biological targets such as kinases and GPCRs. Its bromine functionality allows for further derivatization via cross-coupling reactions, making it valuable in structure-activity relationship studies.
