p2np

Hey folks, going through my notes (read below) I am wondering about three main questions right now: My questions now are: What PH do I need to bring the reaction to before adding DCM? Is it necessary to extract the aqueous phase with IPA or can I just extract with DCM and distill after...

Hey folks, as I am ordering my first P2NP soon I am looking for advice for the following subject: Recrystalization of P2NP I have read some things about this process in the forum and understood that it is recommended not only proof the quality of the P2NP but also to improve it's quality if...

Dear Breaking Bad Community, I am Koko, I have been active on the DN since a few weeks. Since 4-5 months I am on the mission to understand the synthesis of Amphetamine Freebase. Mainly I am looking for 2 synthesis methods: 1. Manufacture Amphetamine Freebase from P2NP & Mercury (II) Nitrate...

Hi, how much amphetamine I can synthesis from 1kg of P2NP?

Introduction At the moment, there are many ways to synthesize dextroamphetamine. They can be divided into 3 types: biosynthesis (using biomass), direct synthesis, and synthesis of racemic (the sum of l- and d-isomers) amphetamine followed by separation of optical isomers. In our case, a...
