1 Aminoethanol

1-Aminoethanol is the 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 substitutents, 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-Aminoethanol is suggested as intermediate in Strecker reaction of alanine synthesis.
