How do I purify ionizable organic amine compounds using flash column chromatography? For most organic reaction mixture purifications the process is fairly straightforward. Use hexane/ethyl acetate or, for polar compounds, DCM/MeOH. But what do you do if this doesn’t work and your compounds are basic organic amines? In this post, I re-examine the options available to achieve an acceptable organic amine purification when typical separation methods are insufficient.
