This invention provides a novel method that is simple, efficient, and allows for a reliable production of fluorine- 18 (18F) radiofluorinated compounds and radiopharmaceuticals. The method comprises an "in-loop" process, where an 18F source is reacted with a precursor compound in an injection loop of a high-performance liquid chromatography (HPLC) system to form a radiolabeling reagent. The [18F]triflyl fluoride, the radiolabeling agent, is reacted with 1,4-dinitrobenzene to form [18F] l-fluoro-4-nitrobenzene, which was then reacted with compounds of interest. The invention provides 18F radiolabeled compounds in high radiochemical yield. The resulting compounds have use as radiotracers and PET imaging agents. The method can also be used to produce 19F compounds.
这项发明提供了一种新颖的方法,该方法简单、高效,并且能够可靠地生产氟-18(18F)放射性氟化化合物和放射性药物。该方法包括一个“循环中”过程,其中将18F源与高绩效液相色谱(HPLC)系统的注射环中的前体化合物反应,形成放射性标记试剂。放射性标记剂[18F]三氟甲磺酸与1,4-二硝基苯反应,形成[18F] l-氟-4-硝基苯,然后与感兴趣的化合物反应。该发明提供了高放射性化学产率的18F放射性标记化合物。所得化合物可用作放射性示踪剂和PET成像剂。该方法也可用于生产19F化合物。
