Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) involving piperazine derivatives. Its structure allows for selective modifications, making it valuable in medicinal chemistry for creating analogs with improved bioavailability and receptor binding. Commonly employed in research settings for designing central nervous system (CNS) agents and receptor modulators due to the presence of the fluoroethyl group, which can influence metabolic stability and lipophilicity. Also utilized in the preparation of radiolabeled compounds for positron emission tomography (PET) imaging studies.
