There's some writing about it, mid-90s from newsgroup,
alt.drugs.chemistry. Eleusis (legend) talks at length about 4-MAR and its synthesis. Circa 2003 a novel synthetic route to the specific enantiomer,
trans-4-methylaminorex, emerged on The-Hive.ws. By 2004 there was a Federal case in Florida of a clandestine chemist producing both
cis-4-MAR and
trans-4-MAR. Only the
cis enantiomer is specifically scheduled and the U.S. federal govt. failed to convict the defendant on charges involving the
trans product on hand at the time of arrest. He still got 48 months for the
cis portion, but even the infamous Analogue Act did not apply here. So this specific enantiomer is a gray market specific drug. Oh and unlike what the govt. expected, the
trans enantiomer is not just active, but it's a bit more potent than the illegal
cis counterpart.
Depends on what you're comparing it to, though. Compared to a typical MDMA dose, yes, 2C-B is nearly ten times more potent. But compared to LSD, well, I think you see where I'm going with this.
Not as much as you might think. The traditional route makes use of cyanogen bromide (BrCN), which is both deadly toxic and known for becoming explosively unstable upon degradation from impurities, which can happen rapidly in the right conditions. This can be a bit daunting, but it's otherwise fairly straightforward.
Alternatively there's a nifty one-pot synth from norephedrine (PPA, aka: cathine) using Potassium Cyanate (KOCN) to reach a urea intermediate which is then hydrolyzed by the addition of HCl, a little clean up and presto: 4-MAR. This manages to avoid dealing with BrCN and targets the legally ambiguous
trans enantiomer, making for an unattractive target to most would-be prosecutors. This is the original Hive Thread:

(note: illicit manufacturing is super dangerous both in terms of physical safety and the endangerment of human lives, and in terms of the numerous and significant legal risks involved; please do not break any laws; this is for academic understanding only).
Yeah if you can find it. No one seems willing to manufacture it these days, even though it should be quite easy for an RC manufacturer in the East, and despite the lowered liability afforded in the
trans enantiomer, as explained above.
Compared to 4-MMC, it has significantly more dopaminergic and adrenergic activity and less serotonergic involvement, which is a bit disappointing, particularly as I've enjoyed the buzz/rush of 4-MMC quite a bit in the past.
Regardless, 3-MMC is an okay stim w/a nice entactogenic aspect to its effects. It's nothing as spectacular as MDMA, but I can tell there's 5-HT activity behind my eyes. This is nice if you want to go out partying with friends, but wish to avoid Karaoke Tuesday® at The Suicide Shack™ & The E-Tard MDMA Hillbilly Hangover Blues brought to you live and direct by MDMA Comedowns, LLC if you catch my drift. That said, if 3-MMC's price is still super low like it was, then it's a great deal, totally worth it. One thing to consider though: 3-MMC is likely prosecutable in the U.S. via the Analogue Act for being so similar to 4-MMC which
is specifically scheduled. Sorry to everyone in EU, Aus, NZ, et al., but I'm not as familiar with foreign drug law.
