title: [Use of mass spectrometry in the chemical analysis of organophosporus compounds].
abstract: The authors studied the possibility of using mass spectrometry in the chemical analysis of the biologically highly active organophosphorus compounds. The results show that methylthiophosphorous acid O-ethyl-S-(2-dimethylaminoethyl) ester has the most complex mass spectrum of all the substances under study. In the spectrum characteristic fragments were detected, having m/e values of 42, 44, 58, 71 and 72 [corresponding to the presence of the (CH3)2NCH2CH2-group], and 81, 95, 97, 105 and 125 which are characteristic of the phosphoester group. Mass spectrometric analysis, performed in this study, proved that the MS method is suitable for a qualitative analysis of biologically highly active organophosphorus compounds such as methylthiophosphorous acid O-ethyl-S-(2-dimethylaminoethyl) ester.
