Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active compounds. Its structure supports the creation of chiral molecules important in antidepressant and anxiolytic drugs. The amine group allows for easy functionalization, making it valuable in medicinal chemistry for building complex drug molecules. It is also employed in the preparation of bioactive heterocycles and in structure-activity relationship (SAR) studies to optimize drug efficacy and selectivity.
