Full name of the substance known in the research chemical circles as 3-FPM or PAL-593 is 3-Fluorophenmetrazine, and it belongs to the group of phenetylamines, specifically its subgroup of amphetamines. Much like other compounds from this class, it contains a phenyl ring bonded to an amino group, though 3-FPM is a variation that contains a fluorine group attached to the phenyl ring at the third position. Structurally speaking, 3-FPM can be described as a cyclic analogue of ephedrine, while in terms of synthesis it represents a fluorinated derivative of phenmetrazine.
