Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the production of selective norepinephrine reuptake inhibitors. It plays a key role in the development of certain antidepressant and central nervous system stimulant drugs due to its chiral structure, which influences biological activity. The compound is also utilized in research settings for the preparation of chiral amines and as a building block in asymmetric synthesis. Its derivatives are explored for potential use in treating neurological disorders.
