Gas chromatographic and mass spectrometric characterization of terbufos sulfoxide and its hydration product.
Abstract Terbufos sulfoxide is a primary metabolite of the organophosphorus insecticide terbufos. The identification of terbufos sulfoxide was determined by combined gas chromatography/mass spectrometry and the direct probe. Mass spectral data are presented and discussed. The data indicate that thermal degradation occurred in the heated GC column. A hydration product of terbufos sulfoxide was detected and its mass spectral data are discussed.
