Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. It serves as a building block for bioactive molecules due to its structural similarity to isoquinoline alkaloids, which are known for their neurological activity. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies targeting dopamine and serotonin receptor modulators. Also utilized in the preparation of inhibitors for enzymes involved in neurodegenerative diseases. Its bromo functional group allows for further derivatization via cross-coupling reactions, making it valuable in drug discovery and development.
