Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. Its structure allows for selective binding and modification in drug design, making it valuable in creating analogs with improved metabolic stability and bioavailability. Commonly employed in the preparation of receptor modulators, especially those targeting neurological disorders such as depression, anxiety, and neurodegenerative diseases. The amine functionality enables easy derivatization for building more complex molecules, while the cyclobutyl and aromatic groups contribute to enhanced lipophilicity and target affinity. Widely utilized in medicinal chemistry research and early-stage drug discovery programs.
