Abstract
For the detection and structural analysis of cathinone-based compounds subject to comprehensive regulation, three MS/MS measurements are repeated for a target sample: an MRM measurement; a product-ion scan measurement; and a product-ion scan measurement. Based on the positional coincidence of a peak on chromatograms obtained by the three measurements, non-cathinone-based compounds are excluded. From the MRM transition and the product-ion spectrum pattern, the kinds of functional groups are estimated and the structure of the cathinone-based compound is estimated.
