1-Aminoethanol
Chemical compound / From Wikipedia, the free encyclopedia
1-Aminoethanol is an organic compound with the formula CH3CH(NH2)OH. It is classified as an alkanolamine. Specifically, it is a structural isomer of 2-aminoethanol (ethanolamine). These two compounds differ in the position of the amino group. Since the central carbon atom in 1-aminoethanol has four different substituents, the compound has two stereoisomers. Unlike 2-aminoethanol, which is of considerable importance in commerce, 1-aminoethanol is not encountered as a pure material and is mainly of theoretical interest.

1-Aminoethanol exists in a solution of acetaldehyde and aqueous ammonia.[1]
1-Aminoethanol is suggested as intermediate in Strecker reaction of alanine synthesis.[2]
1-Aminoethanol was first prepared in 1833 by the German chemist Johann Wolfgang Döbereiner; its empirical formula was first determined by the German chemist Justus von Liebig in 1835.[3] The structure of 1-aminoethanol remained unproven until 1877, when the German-Italian chemist Robert Schiff showed that the structure was CH3CH(OH)NH2.[4]
