Epinephrine, Norepinephrine, and Dopamine are all catecholamines, which means they all have a catechol core (1,2-Dihydroxybenzene). The only one that lacks a hydroxy moiety on the phenyl group is Phenylephrine (known under the brand name Sudafed® among many others). Moreover Nor- means a lack of carbon which is the N-methyl group that lacks in the structure of Norepinephrine.
