I've gotten this ranking from someone that’s very experienced using this course of RC’s which I found exciting: HPLC TOF and GC-MS two significant peaks for C12H17NO and exact same mass spectra; NMR: a mix of two extremely identical compounds (probably diastereoisomers) in approx. molar ratio 3:2 5F-MN-24 and NNEi http://jeremiah1i78cqa1.blogthisbiz.com/profile
