Application

N,N-Dimethylethylamine (DMEA) is generally used to prepare water-soluble quaternary ammonium salts. It facilitates lithium hexamethyldisilazide (LiHMDS) mediated enolization of highly substituted aryl ketones. Additionally, DMEA is also used as an organic solvent in synthetic chemistry.
