Thanks Azo, good informative thread
Been researching a bit over the wk/end and I think methoxydine is shorter name, it's full chemical name is 1-[1-(4-methoxyphenyl)cyclohexyl]-piperidine ....a bit of a mouth full!
Like methedrone is the shorter name for 4-methyl-N-methylcathinone-2-methylamino-1-p-tolylpropan-1-one
"Methoxydine" would be a common name - some vendor probably just recently decided to start selling 4-MeO-PCP under that name.
Now, on the second half, you're doing a few things that i need to correct -
You're stringing two chemical names for mephedrone together - 4-methyl-n-methylcathinone (or 4-methyl-methcathinone) is not a IUPAC-correct name, but is in common use. It's often more useful when describing chemicals that are similar to better known chemicals, to name them in relation to that other chemical. IUPAC names are harder to interpret. The IUPAC name of mephedrone would be the 2-methylamino-1-(4-methylphenyl*)propan-1-one.
However, that's Mephedrone. Methedrone is 4-methoxy-methcathinone (2-methylamino-1-(4-methoxyphenyl)-propan-1-one), which is the beta-ketone analog of PMMA. While it is not as spectacularly dangerous as the amphetamine, it's still bad news, and reports abound of long-term sideffects from methedrone abuse - it's far worse than mephedrone, and most vendors have stopped stocking it after all the reports of negative effects from it.
*4-methylphenyl is the IUPAC naming of p-tolyl - because a benzene ring stuck on something is a phenyl group, while methylbenzene is commonly called toluene, hence, tolyl - p being para, meaning the substituent is at the opposite end, serving the purpose of the 4 (if you number the carbons on the benzene ring, the one opposite the first carbon would be carbon 4).
