Also known as 2,5-dimethoxy-4-isopropoxyphenethylamine, 2,5-dimethoxy-4-(1-methylethoxy)-benzeneethanamine, 4-isopropoxy-2,5-dimethoxyphenethylamine, 2-{2,5-dimethoxy-4-[(propan-2-yl)oxy]phenyl}ethan-1-amine, 2-[2,5-dimethoxy-4-(propan-2-yloxy)phenyl]ethan-1-amine
2C-O-4, also known as 4-isopropoxy-2,5-dimethoxyphenethylamine, is a phenethylamine of the 2C family. It is also a positional isomer of isoproscaline and was probably first synthesized by Alexander Shulgin. It produces hallucinogenic or psychedelic effects. Because of the low potency of 2C-O-4, and the inactivity of 2C-O, Shulgin felt that the 2C-O series would not be an exciting area for research, and did not pursue any further analogues.
