Sulfur mustard (HD) undergoes hydrolysis to form various products such as thiodiglycol (TG) in biological and environmental systems. TG is a precursor in the production of HD and it is also considered as a "Schedule 2" compound (dual-use chemicals with

Environmental research, 106(3), 289-295 (2007-06-01)
A special group of substances that are very dangerous for the biosphere includes war gases such as mustard gas (bis(2-chloroethyl)sulphide). The influence of mustard gas hydrolysis products (MGHPs) on soil microbiota has been investigated. These substances bear numerous toxic effects

Sulfur mustard (HD), or bis(2-chloroethyl)sulfide, has several urinary metabolites that can be measured to assess human exposure. These metabolites include the simple hydrolysis product thiodiglycol (TDG) and its oxidative analogue, TDG-sulfoxide, as well as metabolites of the glutathione/b-lyase pathway 1,1'-sulfonylbis[2-(methyl-sulfinyl)ethane]

Journal of hazardous materials, 167(1-3), 1192-1197 (2009-03-11)
Modified titania nanotubes have been studied as powder decontaminants against sulphur mustard (HD), a deadliest chemical warfare agent. Decontamination reactions were carried out at room temperature (30+/-2 degrees C) and monitored by gas chromatography and gas chromatography mass spectrometry techniques.

Journal of chromatography. A, 1061(2), 235-241 (2005-01-12)
A method for determining thiodiglycol (TDG), a mustard gas hydrolysis product in water, serum and urine samples using gas chromatography-mass spectrometry (GC-MS) after tert-butyldimethylsilylation (TBDMS) is described. Quantitation of TDG was performed by measuring the respective peak area on the
