General description

N,N-Dimethylformamide-d7 (DMF-d7) is a deuterated derivative of N,N-dimethylformamide. It has an isotopic purity of 99.5atom%D. It is a standard purity solvent suitable for routine NMR analyses (conducted at ambient temperatures where quality is less critical). It participates as a solvent to evaluate the solvation of 1.7molar solution of lithium chloride (LiCl) by pulsed neutron diffraction studies.[1] Quadrupole splittings and quadrupole coupling constants of DMF-d7 oriented in a nematic phase have been evaluated by deuteron magnetic resonance studies.[2] DMF-d7 is being considered as a potent anti-cancer drug.[3]

Application

N,N-Dimethylformamide-d7 may be used to study its metabolism in rats by 2H NMR spectroscopy.[4]
