Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its structure supports the creation of bioactive molecules due to the presence of reactive sites like hydroxyl and amine functionalities. Commonly employed in medicinal chemistry for constructing isoquinoline-based compounds, which show potential in treating neurological disorders. Also utilized in research settings for designing enzyme inhibitors and receptor modulators. Its protected amine group allows for selective reactions in multi-step organic syntheses, making it valuable in drug discovery and development.
