Application
This bis(neopentyltrimethylammonium) oxalate is used in the elution step of the Ritter lab′s new method for deoxyfluorination of phenols. First, an Fmoc-protected ruthenium tyrosine amino acid derivative ([CpRu(Fmoc-tyrosin)]CF3CO2, cat# 902314) is incorporated to a peptide. Later, bis(neopentyltrimethylammonium) oxalate and chloroimidazolium chloride (cat# 904848) facilitate the elution of [18F]fluoride. The final [18F]fluoride radiolabeled polypeptide is useful in positron emission tomography (PET) imaging for the study of various biological applications.

Radiolabeled receptor-binding peptides are an important class of positron emission tomography tracers owing to achievable high binding affinities and their rapid blood clearance. Herein, a method to introduce a 4-[18 F]fluoro-phenylalanine residue into peptide sequences is reported, by chemoselective radio-deoxyfluorination
