Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring stereochemical control. Its hydroxyl and amine functionalities allow for selective derivatization, making it valuable in creating structurally complex molecules such as kinase inhibitors, antiviral agents, and central nervous system modulators. Commonly employed in medicinal chemistry for scaffold optimization due to its favorable ring structure and ability to enhance metabolic stability and solubility in drug candidates.
