Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of local anesthetics and antiarrhythmic drugs. Its structure supports the creation of active compounds that interact with ion channels in nerve and cardiac tissues. Commonly employed in research settings for designing new bioactive molecules due to the aromatic and amine functionalities that enhance binding selectivity. Also utilized in the preparation of chiral catalysts and ligands in asymmetric synthesis, contributing to the production of enantiomerically pure drugs.
