Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of local anesthetics and antiarrhythmic drugs. It serves as a building block in organic chemistry for creating nitrogen-containing heterocyclic compounds. Also employed in research settings for developing new bioactive molecules and in the preparation of chiral catalysts for asymmetric synthesis. Its hydrochloride salt form enhances stability and solubility in aqueous environments, making it suitable for laboratory and industrial applications.
