Doing without water: The 18F labeling of radiopharmaceuticals requires nearly anhydrous solutions of [18F]fluoride. Aqueous K2CO3 is generally used to elute [18F]fluoride from an anion‐exchange resin. Replacing aqueous K2CO3 with strong organic bases, such as the phosphazene base P2Et (conjugate acid shown), enabled the recovery of highly reactive [18F]fluoride and avoided the azeotropic evaporation
不用水:放射性药物的18 F标记需要[ 18 F]氟化物的几乎无水的溶液。K 2 CO 3水溶液通常用于从阴离子交换树脂中洗脱[ 18 F]氟化物。用强有机碱(例如磷腈碱P 2 Et(显示共轭酸))代替K 2 CO 3水溶液,可以回收高反应性的[ 18 F]氟化物,并避免了水的共沸蒸发,这在水处理中非常困难。芯片设备。
