Question: is dmso a strong base?
Answer: DMSO is a polar aprotic solvent and is less toxic than other members of this class, such as dimethylformamide, dimethylacetamide, N-methyl-2-pyrrolidone, and HMPA. ... Because DMSO is only weakly acidic, it tolerates relatively strong bases and as such has been extensively used in the study of carbanions.
