O-mustard
Sign in to saveAlso known as agent T, 2,2′-bis(2-chloroethylthio)diethyl ether, bis(2-chloroethylthioethyl)ether
O-mustard (T) is a vesicant chemical weapon, a type of mustard gas, with around three times the toxicity of the original sulfur mustard. It was developed in England in the 1930s as a thickener for mustard gas to make it more persistent when used in warm climates. A mixture of 60% sulfur mustard and 40% O-mustard also has a lower freezing point than pure sulfur mustard, and was given the code name HT. O-mustard is a Schedule I substance under the Chemical Weapons Convention.
