Mustard gas, the common name for dichlorodiethylsulfide, is an organic compound with the chemical formula C4H8Cl2S. It is named because it is volatile and has a taste like mustard. Mainly used in organic synthesis, medicine (can be used to treat some hyperproliferative diseases) and the manufacture of military poison, and because of its widespread use in the poison is notorious.
