To improve the automated synthesis technology of 18F-fluoroacetate (18F-FAC) as tumor imaging agent
the one-pot procedure at TRACERlab FXF-N module was tried. 18F-FAC injection was obtained via a two-step reaction including nucleophilic fluorination of the precursor benzyl bromoacetate with 18F-fluoride and subsequent hydrolysis of the protecting group with 3 mol/L NaOH at the same reaction vessel
and purification with HPLC system. 18F-FAC was automatically synthesized with an uncorrected radiochemical yield of more than 45% and radiochemical purity of more than 99% in the synthesis process of about 50 min. 18F-FAC injection is easy to be obtained and can be used for clinical and scientific study with positron emission tomography (PET) imaging.
