A rapid micro-scale synthesis of fluorinated neuroleptics with extremely high chemical purity was accomplished using a new single column reverse-phase HPLC purification procedure that employs a strongly alkaline eluent to clearly separate F-labeled compounds from the large excess of nitro or chloro precursor. The method is applicable to the production of 18F-labeled positron emission tomography (PET) tracers with high specific activity.
该方法采用新型单柱反相高效
液相色谱纯化程序,利用强碱性洗脱液将 F 标记化合物从大量过剩的硝基或
氯前体中清晰分离出来。该方法适用于生产具有高特异活性的 18F 标记正电子发射断层扫描(PET)示踪剂。
