2-Dimethylaminoethanol (DMAE/deanol) is an amino alcohol. It is the main product formed during the amination of ethylene glycol by dimethylamine on alumina supported copper in a continuous fixed-bed reactor. DMAE has been reported to be the putative precursor of acetylcholine. Its effect as a skin-firming and anti-wrinkle agent has been studied. Microwave spectrum of 2-dimethylaminoethanol has been investigated. Its effect as an organic additive on deposition and anti-reflective properties of porous CaF2 has been studied. Removal of the benzyl ester groups by transesterification with 2-dimethylaminoethanol from benzyl protected tripeptides has been reported.

2-Dimethylaminoethanol (deanol, DMAE) is a precursor of acetylcholine. Microwave spectral studies on DMAE have reported the following values; the rotational constants (MHz) A = 5814. 0(2), B = 2214. 54(2), and C = 2037. 96(2) and a dipole moment of 2. 56 D, with a, b, and c components (D) of 2. 27(2), 0. 3(1), and 1. 16(5), respectively.
