3F-PhenETrazine - 3-ethyl-2-(3-fluorophenyl)morpholine
3-fluoro-phenetrazine
AKA 3-FPE, 3-ethyl-2-(3-fluorophenyl)morpholine
This is the "alpha ethyl" homolog, with an extra carbon, of everyone's much beloved
3F-phenmetrazine. It's also the
meta-fluorinated analog of
phenetrazine.
Presumably, like the other phenylmorpholines, the commercial material is the more active (+/-)-
trans configured isomers, assuming it was made the "easy" synthesis route
I can't find too much online about this (I guess everyone is just hooked up to the 3-FPM cargo cult

), but from my initial experiments it seems to be quite similar to 3-FPM. It's every bit as effective a stimulant at 50mg.
Given the differences between 3-FPM and phenmetrazine, this could be expected to be more potent and more dopaminergic than phenetrazine. I am not certain how its potency compares to 3FPM in terms of binding affinity but it
seems to me slightly more potent. There is not a lot of published data about the higher homologs of phenmetrazines, I don't think. I cannot find binding affinity for any of the 3-ethyl-2-phenyl morpholines at this juncture. I suspect the SAR is similar to that of the cathinones though, which would make this more potent than 3-FPM and possibly even closer to the "next MDPV"....
It would be good if people could post their experiences, or better, if they've come across any references.
