Abstract
Abstract Ethylphosphonothioic dichloride reacts selectively with bifunctional compounds containing OH, NH2 and COOH groups to form derivatives which are stable to gas chromatography. These derivatives can be determined at the low picogram level with nitrogen—phosphorus detector or with the flame photometric detector. The cyclic ethylphosphonothioic derivatives produce characteristic mass spectra with prominent molecular ions. The derivatives are suitable for identification purposes by gas chromatography—mass spectrometry and the prominent ion [M C2H5S]+ should be useful for trace analysis by single ion monitoring.
