It's norephedrine, I tried it got white powder bitter like ephedrine and reacts like ephedrine but it's norephedrine and cannot be used to produce methamphetamine

Science is interesting and Chemistry is sweet but My high school teacher never told me

Please great chemist expert can we replace Dichloromethane with toulene or ethyl acetate for extraction of meth from the reaction above

Please I want to synthesize ephedrine HCl, who will teach me

Boss, Ephedrine synthesis from methcathinone, I have another question here, this is a paragraph in the procedure for making ephedrine hcl, After the addition of the entire amount of sodium borohydride, the reaction mixture is stirred for 24 hours. Figure 4 Great chemist can we skip this 24...

After the addition of the entire amount of sodium borohydride, the reaction mixture is stirred for 24 hours. Figure 4 Great chemist can we skip this 24 hours stirring of reaction mixture by heating again for 40 minutes at 40°c.
