A rapid and simple colorimetric test for 2,2,2-cryptand (Kryptofix 2.2.2.) in solution†
Abstract
A new and versatile method for 2,2,2-cryptand determination in [18F]-labeled radiotracers is described. Proof of concept and applicability of the test method for the commercial radiotracer [18F]-FDG and model compounds FLT and FMISO were also proven.
