Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of beta-blockers and other cardiovascular drugs. Its epoxide ring allows for selective ring-opening reactions, enabling the introduction of functional groups with high stereochemical control. Commonly employed in asymmetric synthesis to introduce fluorinated aromatic moieties into complex molecules, enhancing metabolic stability and bioavailability in drug candidates. Also utilized in the development of radiolabeled compounds for positron emission tomography (PET) imaging due to the presence of fluorine-18 potential labeling sites.
