Liquid chromatography–time-of-flight mass spectrometry analysis of 1-(2-chloroethoxy)-2-[(2-chloroethyl)thio] ethane and related compounds: Separation of an eleven component mixture

A method of separation for an eleven component mixture comprised of 1-(2-chloroethoxy)-2-[(2-chloroethyl)thio] ethane (4) and its derivatives has been developed using LC–time-of-flight-MS. All analytical figures of merit for compounds 1–11 have been determined. Compound 4 was examined in a substrate extraction study consisting of different sand and soil matrices, and a hydrolysis study of 4 on sand revealed an extremely complex degradation pathway which appeared to be concentration dependent. Substrate extraction and hydrolysis results where compared with sulfur mustard (HD).
