The consequent lack of carbon monoxide (CO) from the acylium ion outcomes within the formation of the phenyl cation, as indicated in Figure 4. The phenyl (m/z 77), methylphenyl (m/z 91), and fluorophenyl (m/z 95) cations are some consultant examples of ions produced by the lack of carbon monoxide from the corresponding acylium ions at m/z 105 (benzoyl ion), 119 (methylbenzoyl ion) and 123 (fluorobenzoyl ion). Though these fragmentation patterns within the mass spectra provide structural data about the elemental composition, they don’t differentiate structural isomers with completely different substitution patterns on the aromatic ring. Sadly, the EI method is often restricted to differentiate structurally comparable cathinones. Not all substituted cathinones may be directly derivatized using TFAA, which requires, not less than, one hydrogen atom in the amino group or an energetic hydrogen atom from different purposeful teams (e.g., -OH, -COOH). After derivatization and understanding the molecular weight and ions resulting from fragmentation, it was attainable to determine the chemical buildings of the formed compounds.

The singlet at 2.Eighty two ppm integrates 3 protons and belongs to the N-methyl group (H-1″), while the doublet at 1.Sixty four ppm corresponds to the terminal methyl group of the alkyl aspect chain (H-3) that had been confirmed by the COSY experiment (Determine 7). Within the 13C NMR spectrum the indicators from the eleven carbon atoms had been assigned primarily based on two-dimensional experiments 1H-13C HSQC and HMBC (Figure 8). The carbon indicators corresponding to the phenyl ring were noticed at 108.5 (C-2′), 109.1 (C-5′), 127.Zero (C-6′), 127.Three (C-1′), 148.9 (C-3′) and 154.1 ppm (C-4′), while the methylenedioxy group (C-7′) produced a sign at around 103 ppm. The carbonyl carbon (C-1) was discovered at 195.9 ppm, and the methine carbon (C-2) and the two methyl groups C-1″ and C-3 appeared at 59.9, 31.5 and 16.3 ppm, respectively. NMR spectra of methylone found in product 10. (A) 1H-13C HSQC and (B) 1H-13C HMBC. Analytical knowledge for products 3-7 revealed the presence of methedrone along with different cathinones, namely N-ethylcathinone and buphedrone.
