Forgive my ignorance,
I have next to no chemistry knowledge, but am wondering about possible legal complications with some of these.
Correct me if I'm wrong but this is an isomer of phendimetrazine, having the methyl in the N and alpha positions vs 2 in the five position, is it reasonable to think phendimetrazine may be a possible impurity?
I was wondering the same thing about 5-methyl-2- phenylmorpholine and phenmetrazine itself...
As I said I am no chemist and have no idea if this is likely or even possible, I use the example of 3 and 4-mmc?
Roi you seem very knowledgeable, thoughts?
Perhaps sekio would be kind enough to weigh in?
