Sesquimustard (military code Q) is the organosulfur compound with the formula (ClCH2CH2SCH2)2. Although it is a colorless solid, impure samples are often brown. The compound is a type of mustard gas, a vesicant used as a chemical weapon. From the chemical perspective, the compound is both a thioether and an alkyl chloride.
Because sesquimustard is a solid at room temperature, it is not as easily deployed as related liquid mustards. It was only ever deployed as mixtures with the original mustard, with phosgene, or as a solution. Since 1997, it has been listed under Schedule I of the Chemical Weapons Convention, as a substance with few uses outside of chemical warfare[1][2][3] (although since then, it has been found to be useful in chemotherapy).[4]
