nabh4

CAS number: 16940-66-2 Hill molecular formula: H₄BNa Chemical formula: NaBH₄ Molar mass: 37.83 g/mol Boiling point: 500℃ (decomposition) Density: 1.07g/cm3(20℃) Explosion limit: 3.02 %(V) Flash point: 69 °C Not applicable Flash point: 220℃ Melting point: >360℃ (slow decomposition) pH value: 11...

After nabh4 addition is complete and mixed for a few hours after can you let the mix sit for a few hours and the freebase oil layer will rise to the top and can be seperated? this eliminates the need for dcm or toluene extraction but does effect yield.

https://bbgate.com/threads/one-pot-amphetamine-synthesis-from-p2np-with-nabh4-cucl2-1kg-scale.70/ Can I use STAB instead of NabH4 in this route, people in the forum say that STAB can be used in case of glacial acetic acid

Nabh4 is not available for personal purchase in my country, so I wonder if anyone has used STAB instead of Nabh4, as far as I know STAB is a mild reducing agent, but I don't know if it can reduce P2NP, and cyanoboron Sodium hydride is highly toxic and I'm not going to try this, if anyone has...

Well Howdy there folks! There’s a lot of info and conversations and loosely, reliable syntheses on many forums discussing using 2 particular reagents, but I need something objective. I’m looking for this “gold standard” synth everyone is having success with using Sodium Borohydride and...

Amphetamine synthesis via NaBH4 reductive amination from P2NP. https://bbgate.com/threads/one-pot-amphetamine-synthesis-from-p2np-with-nabh4-cucl2-1kg-scale.70/

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...

Introduction I represent to BB audience Methamphetamine synthesis method of 1-phenyl-2-propanon (P2P) reductive amination by NaBH4. Following method allows obtaining and large batches of product. The hardest problem of this method is the heat generating during exothermic reaction of imine...
