Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of central nervous system agents. It serves as a building block for certain antihistamines and antidepressants due to its amine functionality and aromatic structure. Also employed in research settings for the preparation of chiral catalysts and ligands in asymmetric synthesis. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in aqueous reaction conditions.
