Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) active agents. Its rigid cyclobutane structure with an aromatic substituent makes it valuable for modifying pharmacokinetic properties such as metabolic stability and target selectivity. It is employed in the preparation of selective enzyme inhibitors and receptor modulators, especially in research focused on neurological disorders. Additionally, it serves as a chiral building block in asymmetric synthesis, enabling the creation of structurally complex drug candidates. Its hydrochloride salt form enhances solubility and stability, facilitating handling and formulation in medicinal chemistry workflows.
