Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceuticals. Its chiral amino alcohol structure makes it valuable in asymmetric synthesis, where it serves as a building block for drugs targeting central nervous system disorders and cardiovascular diseases. Commonly employed in the preparation of β-blocker analogs due to the presence of the fluorophenyl and hydroxyethyl motifs, which are known pharmacophores in adrenergic receptor antagonists. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies, enabling optimization of drug candidates through selective modification of functional groups.
