A high-performance liquid chromatography-tandem mass spectrometric method (LC/MS/MS) was developed and validated for the quantitative analysis of Kryptofix (K-222) in the radiopharmaceuticals of 2-deoxy-2-[(18)F] fluoro-D-glucose (2-[(18)F]FDG) and 3-(3-((3-fluoropropyl)thio)-1,2,5-thiadiazol-4-yl)-1,2,5,6-tetrahydro-1-methylpyridine (FPTZTP). With an internal standard, the limit of quantitation for K-222 was

This work shows how the inclusion of cryptand 222 as a leading electrolyte additive in isotachophoresis affects the electrophoretic mobilities of alkali metal cations. Using isotachophoresis the separation of alkali metals can be difficult due to the similar electrophoretic mobilities

Radiopharmaceutical solutions of 2-[18F]fluoro-2-deoxy-D-glucose (2-[18F]FDG) prepared via an aminopolyether-supported nucleophilic-substitution mechanism were analyzed for contaminant 4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo-[8,8,8]-hexacosane (Kryptofix 2.2.2). Washing the C18-immobilized [18F]fluoro-tetraacetylated intermediate with 10 mL 0.1 M HCl was found to remove impurity Kryptofix 2.2.2 from the final product.
