Used in the synthesis of pharmaceutical intermediates, particularly in the development of central nervous system agents. It serves as a chiral building block in the production of selective serotonin reuptake inhibitors (SSRIs) and related antidepressant drugs. Its stereochemistry plays a critical role in enhancing drug efficacy and reducing side effects. Commonly employed in research settings for optimizing asymmetric synthesis routes and improving yield in active pharmaceutical ingredient (API) manufacturing.
