Used in the synthesis of pharmaceuticals, particularly as a chiral building block for drugs targeting the central nervous system. It serves as an intermediate in the production of certain antidepressants and anti-Parkinson agents due to its structural similarity to biologically active phenethylamines. Its chiral amine functionality allows for stereoselective reactions, making it valuable in asymmetric synthesis. Also employed in the development of adrenergic receptor ligands and in research related to neurotransmitter analogs.
