The stability of fluoroalkyl groups as a pendent on the phenyl ring was measured in vitro using rat hepatic microsomes and human serum to predict their in vivo stabilities. We have prepared three [18F]fluoroalkylbiphenyls as the model compounds of fluoroalkyl aromatic compounds to compare the in vitro stabilities. In addition, in vitro stabilities were measured separately using rat hepatic microsomes and human serum at 37 oC. Fluoroethylbiphenyl had similar or slightly superior stability to fluoropropylbiphenyl and these two compounds were much more stable than fluoromethylbiphenyl in vitro.
