Talk:Α-Methylfentanyl

It says that "AMF is less potent by weight" whereas it is actually at least three times the potency of fentanyl.

Chinese Rock has been known since 1975 at least
The article states that Chinese Rock (as a-Methylfentanyl) began to appear in 1976 in Orange County, CA. This is not the earliest known usage by a long shot. It was widely used in the New York Bowery in the early 1970s; by 1975 punk rock icons The Ramones, Richard Hell, and Johnny Thunders had immortalized Chinese Rock in a song called, "Chinese Rock." (Sample lyrics: "Ya wanna go take a walk, ya wanna go cop?  Ya wanna go get some Chinese rock?") See [] for more. Galaxiana (talk) 01:45, 24 December 2015 (UTC)

Isomers
There are 2 isomers. This is an important fact to students. The drug cannot be produced in a chiral manner & partial crystalization would result in losing 50& of the less-potent isomer. Adding is of no value to clandestine chemists since their is no practical solution. Even if someone went to the trouble of isolating the isomers, tautaumerism is not going to work well and you would have to recrystalize many times, with mechanical losses on each loop. It would be x10 more work than the original synthesis. — Preceding unsigned comment added by 81.99.74.135 (talk) 14:08, 14 April 2017 (UTC)
