Ethanimine

CH3CHNH

Definition

Ethanimine is an 8-atom, nitrogen-containing organic molecule that is the next heavier homolog of methanimine (CH2NH). In laboratory experiments involving the irradiation of interstellar ice analogs, it has been suggested that ethanimine is a precursor to the formation of the amino acid alanine.

History

Methanimine was detected in the interstellar medium in 1973 (Godfrey et al. 1973), and ethanimine has more recently been found in the Milky Way’s galactic center molecular cloud Sagittarius
