Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of local anesthetics and antiarrhythmic agents. Its structure supports the creation of compounds that interact with ion channels in nerve and cardiac tissues. It is also employed in research settings for developing novel bioactive molecules due to its amide and amine functionalities, which are common in drug-like structures. The hydrochloride salt form enhances solubility and stability, making it suitable for use in aqueous reaction environments.
