WebHere we present the NMR shifts of the most commonly used solvents and impurities in organic synthesis measured in the 7 most frequently used deuterated solvents. Please … WebCommon solvents include chloroform-D, acetone-D6, benzene-D6, deuterium oxide (D 2 O), DMSO-D6, ethanol-D6, and methanol-D4. Other, less common deuterated solvents can be ordered through Chemistry Stores from Cambridge Isotope Laboratories or Sigma-Aldrich/Isotec . Typical NMR samples contain 0.6-0.7 mL of deuterated solvent.
