    4'-Methylpropiophenone and 2-Bromo-4'-methylpropiophenone on BB Forum

    Where I can find 4'-Methylpropiophenone and 2-Bromo-4'-methylpropiophenone? Due to 4'-Methylpropiophenone CAS 5337-93-9 illegal status (controlled in many countries), it's almost impossible to find it on the DarkNet market. However, there is another direct precursor for mephedrone (4-MMC)...
