Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its rigid cyclobutyl structure with an aromatic substitution pattern makes it valuable for designing molecules with specific receptor selectivity. It is often employed in the preparation of experimental drugs targeting neurological disorders due to its ability to influence bioavailability and metabolic stability. Additionally, its amine functionality allows for easy derivatization, enabling rapid exploration of structure-activity relationships in drug discovery programs.
