Building upon the work of Gottlieb, Kotlyar, and Nudelman in the Journal of Organic Chemistry, signals for common impurities are now reported in additional NMR solvents (tetrahydrofuran-d , toluene-d , 8 8 dichloromethane-d , chlorobenzene-d , and 2,2,2-trifluoroethanol-d ) which are frequently used in
