Distinguishing of 2-MAPB and 6-MAPB: Solution of the problem.
Vadim A ShevyrinYuri M ShafranPublished in: Journal of mass spectrometry : JMS (2018)
Differentiation of new psychoactive substance (NPS), 6-(2-methylaminopropyl)benzofuran (6-MAPB), and its positional isomer, 2-(2-methylaminopropyl)benzofuran (2-MAPB), by means of gas chromatography/mass spectrometry (GC/MS) with quadrupole detection is ambiguous. Reliable distinguishing of the two isomers could be achieved by MS/MS spectra recorded after collision-induced dissociation (CID) of precursor ions. Both electron ionization (EI) and electrospray ionization (ESI) methods could be used for these purposes.
