Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. It serves as a building block for developing central nervous system agents, including potential treatments for neurological disorders. The bromo functionality allows for further cross-coupling reactions, enabling the introduction of various substituents to tailor the molecule’s activity. Commonly employed in the preparation of isoquinoline-based derivatives with potential anticonvulsant, antidepressant, or anticancer properties. Its protected amine group facilitates selective reactions, making it valuable in multi-step organic syntheses.
