Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) where a cyclobutyl amine moiety is required. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex molecules. Commonly employed in the preparation of kinase inhibitors and other bioactive agents. The hydrochloride salt form enhances stability and solubility, facilitating handling and reaction in aqueous or polar organic solvents. Also utilized in research settings for structure-activity relationship (SAR) studies due to the constrained cyclobutane ring influencing potency and metabolic stability.
