2,5-Dimethoxy-4-fluoroamphetamine
2,5-Dimethoxy-4-fluoroamphetamine (DOF) is a psychedelic drug of the phenethylamine and amphetamine classes. Alexander Shulgin briefly describes DOF in his book "PiHKAL": DOF showed some stimulating effects in humans, but no psychedelic activity, after three doses of 6 mg spaced by one hour. Daniel Trachsel further suspected that the molar refraction of the important 4-substituent in DOF and 2C-F may be too low to activate the 5-HT receptor sufficiently. DOF more closely mimics the effects of the 4-unsubstituted 2,5-dimethoxyamphetamine than the effects of DOC, DOB, and DOI. 2,5-Dimethoxy-4-fluoroamphetamine 2,5
