Used primarily as an intermediate in the synthesis of pharmaceuticals and fine chemicals. Its structure makes it valuable in the development of active pharmaceutical ingredients, particularly in the creation of antihistamines and other central nervous system agents. The amine functionality allows for easy derivatization, enabling the formation of amides, salts, and other nitrogen-containing compounds important in drug design. Also employed in research settings for the preparation of chiral catalysts and ligands in asymmetric synthesis. Its hydrochloride salt form enhances stability and solubility, which is beneficial in both storage and reaction processes.
