Substituted phenethylamines (or simply
phenethylamines), also conceptualizable as
dopamine/adrenaline analogues, are
organic compounds which may be thought of as being derived from
phenethylamine itself. The molecular structures of all phenethylamines contain a
phenyl ring, joined to an
amino (NH2) group via an ethyl (-CH
2–CH
2-)
sidechain. In substituted phenethylamines, the phenyl ring, sidechain and/or amino group are modified by substituting another group for one of the hydrogen (H) atoms.
