Synthesis of Ephedrine Hydrochloride and Chemical Analysis

[Rabidreject]

Methcathinone is just as hard to come by as is ephedrine or even pseudoephedrine now that the RC World started going down the cathinone route a while ago now…

Hello, can this sodium borohydride be replaced with active aluminum?

Hi all,

If I can, I would like to use this method for the synthesis of ephedrine for d-methamphetamine synthesis. I am aware that I will need to seperate the isomers of the methamphetamine produced in this case as the ephedrine we end up with in this synthesis is racemic.

Me and my team are planning on working on a method to scale up this synthesis.

Would it be faster and more efficient to manufacture methamphetamine from this synthesis method + the seperation of the 2 isomers or should we work on scaling up the method below:

to get d-methamphetamine straight away?

Thank you to whoever replies to this.

Please can we use this Ephedrine to produce D-meth, please we has actually tried it, please am confuse about this argument that is racemic meth and D-Meth, please give us answer

ConsiderHello, yes, It can be used. There is video tutorial and a detailed write up.

Teacher G.Patton, I respect you, sorry am asking much question,
please Teacher using this ephedrine produced from this method can it yield D-Meth. Without tartaric acid,

ConsiderYes, but you need to use any other appropriate carboxylic acid to separate isomers anyway.
