| Abstract/Summary |
Electrospray ionization (ESI) mass spectra of hexoses, pentoses, and 2-deoxy-2-fluoro-d-glucose (FDG) were investigated and compared using liquid chromatography/mass spectroscopy (LC/MS). 18F-FDG is one of the most widely used radiopharmaceuticals. This work is aimed at the possible interpretations of ESI mass spectra and at the comparison of various pentoses (arabinose, ribose, xylose), and hexoses (glucose, fructose, galactose, mannose) which can be formed during the 18F-FDG’s synthesis or decomposition. As a result, nine major associates were found in the positive and four in the negative mass spectra of all examined saccharides of which intensities and mass can be used with their retention times to determine the saccharide. M · NH4+ and M · COOH− were identified as the most stable associates.
