    “…2-[(18)F]Fluoroethyl azide ([(18)F]FEA) can readily be obtained by nucleophilic substitution of 2-azidoethyl-4-toluenesulfonate with [(18)F]fluoride (half-life 110 min), and has become widely used as a reagent for ‘click’ labeling of PET tracers. However, distillation of [(18)F]FEA is typically required, which is time-consuming and unpractical for routine applications. …”
