Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of active ingredients for central nervous system (CNS) drugs. It plays an important role in the development of selective norepinephrine reuptake inhibitors and other neuromodulatory agents. Due to its structural configuration, it enhances binding affinity and selectivity in drug candidates targeting depression, anxiety, and attention-deficit disorders. It is also employed in the preparation of novel kinase inhibitors and receptor antagonists in medicinal chemistry research.
