N,N-Dimethylethanolamine bitartrate or deanol bitartrate is an organic compound with the chemical formula . It is a white powder. Modern texts refer to the N,N-dimethylethanolamine salt of the natural form of tartaric acid, that is, the salt called N,N-dimethylethanolamine dextrobitartrate, N,N-dimethylethanolamine (2R,3R)-bitartrate or N,N-dimethylethanolamine L-(+)-bitartrate.
N,N-Dimethylethanolamine bitartrate is a N,N-dimethylethanolamine salt of tartaric acid. N,N-Dimethylethanolamine bitartrate contains tertiary ammonium cations (dimethyl(2-hydroxyethyl)ammonium) and bitartrate anions . Tertiary ammonium cation is a cation in which three hydrogen atoms of ammonium are replaced with organyl groups. In this compound, the three substituents of ammonium are two methyl groups and one 2-hydroxyethyl group . The bitartrate anion is chiral (there are left, right and meso forms of bitartrate, see tartaric acid).
N,N-Dimethylethanolamine bitartrate is used in biological studies to evaluate motor activity in response to the injection of N,N-dimethylethanolamine.
