Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring chiral building blocks. Its cyclic structure and amine functionality make it valuable in creating biologically active molecules, including antiviral and central nervous system agents. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to influence potency, selectivity, and metabolic stability. Also utilized in the preparation of heterocyclic compounds for drug discovery research.
