To the best of our knowledge only one determination of iobitridol in biological fluids by HPLC is reported [15]. We approached the NMR spectroscopy with the aim of accomplishing the quantification of the content of iobitridol directly in the final formulation with minimal work up, in short time and by a medium field instrument which is of prevalent and established use in qNMR. The NMR experiments were carried out according to the general principles laid down in the general EP monograph 01/2009:20233 nuclear magnetic resonance spectrometry.
