title: Deuterium NMR spectroscopy of biofluids for the identification of drug metabolites: application to N,N-dimethylformamide.
abstract: The metabolism of N,N-dimethylformamide in the Sprague-Dawley rat has been reinvestigated using NMR spectroscopy of urine. In particular, through the use of N,N-dimethylformamide-d7 (DMF-d7) and 2H-NMR spectroscopy, the principal metabolites of this compound have been confirmed in a direct manner. The use of inverse-detected two-dimensional 2H-13C correlation with 13C decoupling aided metabolite identification through the provision of 13C chemical shifts.
