Usage

General Description

2-HYDROXYETHYL-2-CHLOROETHYLSULPHIDE is a chemical compound used in the development and production of chemical warfare agents. Also known as sulfur mustard, it is a highly toxic and corrosive substance that can cause severe skin burns, respiratory issues, and even death. It is classified as a vesicant, meaning it causes blistering of the skin and mucous membranes upon contact. Due to its extreme toxicity, 2-HYDROXYETHYL-2-CHLOROETHYLSULPHIDE is banned under the Chemical Weapons Convention and its production and stockpiling are strictly regulated by international law. However, it is important to remain vigilant and ensure that this dangerous chemical is not used for malicious purposes.

THE CHARACTERIZATION OF SULFONIUM CHLORIDES BY GAS CHROMATOGRAPHY/MASS SPCTROMETRY AND THE DEGRADATION OF 2-CHLOROETHYL SULFIDE DERIVATIVES

Three aqueous samples containing sulfonium chloride salts of both mustard gas (2,2'-dichlorodiethylsulfide) and its simulant 2-chloroethyl ethyl sulfide have been characterized by gas chromatography/mass spectrometry (GC/MS).Theese salts decompose thermallly to the sorresponding 2-chloroethyl and 2-hydroxyethyl sulfides, therefore GC/MS analysis is not indicative of the true composition of these solutions.Small amounts of dithioethers characteristic of the decomposition of the dimeric salts were also detected.Electron Impact (EI) ionization produces a more intense molecular ion than methane chemical ionization (CI) for the dithioethers because of the ease of formation of sulfonium ions during chemical ionization.The composition products of four aged samples of 2-chloroethyl sulfides (RSCH2CH2Cl where R=methyl, ethyl, phenyl and benzyl groups) were also characterized by GC/MS, which indicated that decomposition of these compounds may proceed via dimeric sulfonium ions.Mustard gas was detected in all but one of the samples, providing evidence for secondary sulfonium cation formation in the degradation prcess.Keywords: Sulfonium chlorides; 2-chloroethyl sulfides; degradation; dimeric sulfonium cations; GC/MS characterization.
