2C-G-3
2C-G-3, also known as 2,5-dimethoxy-3,4-(trimethylene)phenethylamine, is a psychedelic drug of the phenethylamine and 2C families. It is the derivative of 2C-G (2C-G-0) in which the 3,4-dimethyl groups have been connected via an additional carbon atom to form a cyclopentane ring attached to the benzene ring and hence has a dihydroindene ring system.
