2C-EF, or 4-fluoroethyl-2,5-methoxyphenethylamine, is a lesser-known psychedelic drug and a substituted phenethylamine. 2C-EF was referenced in PiHKAL (Phenethylamines i Have Known And Loved) by Alexander Shulgin when talking about the alpha-methyl analogue DOEF.[1] Alexander Shulgin stated "4-(2-fluoroethyl)phenethylamine, it would be every bit as much a treasure and ally as is 2C-B or 2C-I. In fact, I am sure enough about this prediction that I am willing to name the stuff 2C-EF."[2] Very little data exists about the pharmacological properties, metabolism, and toxicity of 2C-EF.
