2,5-Dimethoxy-4-ethylphenethylamine is a colorless oil.  Crystalline forms are obtained as the amine salt by reacting the free base with a mineral acid, typically [[hydrochloric acid]] (HCl).

Shulgin does not report an exact boiling point for the free base, stating only that during one synthesis the fraction boiling between 90 and 100&nbsp;°C at 0.25&nbsp;mmHg pressure was collected and converted to the hydrochloride salt. Shulgin reports the melting point of the hydrochloride salt as 208.5–210.5&nbsp;°C.<ref name="shulginIndex">{{cite book| vauthors = Shulgin AT, Manning T, Daley PF|title=[[The Shulgin Index|The Shulgin Index: Volume 1]]|date=2011|publisher=Transform Press|location=Berkeley, CA|isbn=978-0-9630096-3-0|edition=First}}</ref>
