Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of serotonin-norepinephrine reuptake inhibitors (SNRIs) such as duloxetine. Its enantiomerically pure structure enables efficient and selective drug synthesis, improving the therapeutic profile and reducing side effects. Commonly employed in asymmetric synthesis routes due to the presence of both amine and ester functional groups, allowing for versatile chemical transformations. Widely utilized in the development of antidepressants and treatments for chronic pain conditions.
