NMR Chemical Shifts of Common Laboratory Solvents as Trace Impurities Hugo E Gottlieb * Vadim Kotlyar and Abraham Nudelman* DepartmentofChemistry Bar-IlanUniversity Ramat-Gan52900 Israel ReceivedJune27 1997 In the course of the routine use of NMR as an aid for organic chemistry a day-to-day problem is the identifica-tion of signals deriving from common contaminants (water solvents Many deuterated solvents are available from the stockroom The NMR lab does not supply you with solvents 5) Use Clean Tubes and Caps NMR tubes are available from the stores and after use they should be rinsed with acetone or some other suitable solvent then dried with a blast of dry air or nitrogen Do NOT dry tubes in a hot oven because it does not remove solvent vapour effectively and

NMR Chemical Shifts of Trace Impurities: Common

NMR Chemical Shifts of Trace Impurities: Common Laboratory Solvents Organics and Gases in Deuterated Solvents Relevant to the Organometallic Chemist | Organometallics Tables of 1H and 13C NMR chemical shifts have been compiled for common organic compounds often used as reagents or found as products or contaminants in deuterated organic solvents

Deuterated DMSO also known as dimethyl sulfoxide-d 6 is an isotopologue of dimethyl sulfoxide (DMSO (CH 3) 2 S=O)) with chemical formula ((CD 3) 2 S=O) in which the hydrogen atoms (H) are replaced with their isotope deuterium (D) Deuterated DMSO is a common solvent used in NMR spectroscopy Production Deuterated DMSO is produced by heating DMSO in heavy water (D 2 O)

It should be noted that chemical shifts can be dependent on solvent concentration and temperature u Approximate values only may vary with pH concentration and temperature x Melting and boiling points are those of the corresponding unlabeled compound (except for D2O) These temperature limits can be used as a guide to determine the useful liquid range of the solvents Information gathered

The chemical shifts were read and are presented in Table 1 Except where indicated the coupling constants and therefore the peak shapes are essentially solvent-independent and are presented only once For D 2O as a solvent the accepted reference peak (δ) 0) is

Deuterated drugs: unexpectedly nonobvious?

Initial results from the clinical trials of Auspex's deuterated Effexor[R] and CoNCERT s deuterated Paxil[R] demonstrate the potential success of deuterating known drugs as both trials exhibited a dramatic reduction in the metabolism of the deuterated agent Amanda Yarnell Heavy-Hydrogen Drugs Turn Heads Again Chemical Engineering News June 22 2009 at 36-38 On June 2 2009 CoNCERT
