Identification and structural characterization of synthetic cathinones: N-propylcathinone, 2,4-dimethylmethcathinone, 2,4-dimethylethcathinone, 2,4-dimethyl-α-pyrrolidinopropiophenone, 4-bromo-α-pyrrolidinopropiophenone, 1-(2,3-dihydro-1H-inden-5-yl)-2-(pyrrolidin-1-yl)hexan-1-one and 2,4-dimethylisocathinone

Purpose Seven synthetic cathinone derivatives detected in samples seized in Poland from clandestine laboratories: N-propylcathinone, 2,4-dimethylmethcathinone (2,4-DMMC), 2,4-dimethylethcathinone (2,4-DMEC), 2,4-dimethyl-α-pyrrolidinopropiophenone (2,4-DMPPP) and 2,4-dimethylisocathinone (4-iso-DMC), collected from smartshops: 4-bromo-α-pyrrolidinopropiophenone (4-Br-PPP) or received from an attorney 1-(2,3-dihydro-1H-inden-5-yl)-2-(pyrrolidin-1-yl)hexan-1-one (5-BPDi) were identified and analytically characterized.
