The present invention relates to a method for labelling fluorine-18, which is a radioisotope, and more specifically, to a method for labelling a [
18
F]fluoride in a method for preparing an organic [
18
F]fluoro compound by reacting an alkyl halide or an alkyl sulfonate with a [
18
F]fluoride, wherein a [
18
F]fluoride supported on a quaternary alkyl ammonium polymer support is eluted using a solution containing a metal salt or a quaternary ammonium salt with an adjusted pH, and a base is not additionally used. The present invention enables a labeling reaction without an additional base after precisely reflecting the concentration of a base absolutely necessary for the nucleophilic substitution of a [
18
F]fluoride or eluting a [
18
F]fluoride using a [
18
F]fluoride eluent with an adjusted pH, thereby stably obtaining a [
18
F]fluoride-labelled compound in a high yield, and is thus useful for production of fluorine-18-labelled radioactive medical supplies.
本发明涉及一种标记放射性同位素氟-18的方法,更具体地涉及一种方法,该方法通过将烷基卤化物或烷基磺酸酯与[18F]氟反应,标记[18F]氟化物以制备有机[18F]氟化合物,其中使用含有金属盐或季铵盐的调节pH的溶液洗脱负载在季铵基聚合物支撑上的[18F]氟化物,而不需要额外使用碱。本发明使得在准确反映核子亲核取代所必需的碱的浓度之后,无需额外使用碱进行标记反应,或者使用具有调节pH的[18F]氟洗脱液洗脱[18F]氟化物,从而稳定地高产率地获得[18F]氟标记化合物,因此对于制备氟-18标记的放射性医疗用品非常有用。
