What is the best way to purify p2np crystals to near 100% pure for an amphetamine synthesis? Is re-crystallization recommended?

Hello, yes. 1-Phenyl-2-nitropropene (P2NP) can be recrystallized from hexane, methanol, ethanol or isopropanol (IPA).

thank you. which one of those solvents the best to use?

I think all of them are equivalent. You repeat same questions, which was already discussed in 1-Phenyl-2-nitropropene (P2NP) video synthesis from benzaldehyde and nitroethane topic.
