2-FA

2-FA is a synthetic ring substituted fluorinated amphetamine compound. 2-FA is one part of a series of modern designer fluorinated amphetamine analogs that includes synthetic compounds like 2-FMA, 3-FA, 3-FEA and 4-FA(2-Fluoroamphetamine) is a synthetic ring-substituted fluorinated amphetamine. Molecules of the amphetamine class contain a phenethylamine core featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain with an additional methyl substitution at Rα (i.e. amphetamines are alpha-methylated phenethylamines). Unlike its close analogue 2-FMA, 2-FA does not contain a methyl group bound to the terminal amine RN of the amphetamine core, which renders it structurally and functionally similar to amphetamine. 2-FA is the 2-position fluorinated analogue of amphetamine.
