Used in pharmaceutical synthesis as an intermediate for nitrogen-containing heterocyclic compounds, particularly in the development of kinase inhibitors and antiviral agents. Its structure supports binding to enzyme active sites, making it valuable in medicinal chemistry for optimizing drug potency and selectivity. Also employed in research settings to design novel bioactive molecules targeting central nervous system disorders and inflammatory diseases. The hydrochloride salt form enhances solubility, facilitating use in aqueous reaction systems and biological assays.
