Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceuticals. Its chiral center and functional groups make it valuable for constructing enantiomerically pure molecules, often found in central nervous system agents or cardiovascular drugs. The tert-butyl carbamate group serves as a protecting group for amines during multi-step syntheses, allowing selective reactions at other sites. The presence of fluorophenyl and hydroxyethyl moieties enables further derivatization for structure-activity relationship studies in drug discovery.
