The present invention is directed to a method for preparing an anhydrous
18
F-radiolabeled fluorinating agent by a nucleophilic reaction of a hydrated
18
F-radiolabeled fluoride ion source with an unsaturated carrier compound; treating the
18
F-radiolabeled carrier compound to produce a non-aqueous mixture of the
18
F-radiolabeled carrier compound in a solvent; and reacting the
18
F-radiolabeled carrier compound with a nucleophilic composition in a nucleophilic reaction to produce an anhydrous
18
F-radiolabeled fluorinating agent. The present invention is also directed to an anhydrous
18
F-radiolabeled fluorinating agent comprising the formula [Q

x
. Additionally, the present invention is directed to an
18
F-radiolabeled fluorinated radiopharmaceutical or an
18
F-radiolabeled fluorinated radiotracer prepared by reacting the anhydrous
18
F-radiolabeled fluorinating agent with a drug intermediate. The present invention is further directed to methods for treating a disease or imaging a subject using an
18
F-radiolabeled fluorinated radiopharmaceutical or an
18
F-radiolabeled fluorinated radiotracer.
