History as chemical weapons
Sulfur mustard is a type of chemical warfare agent. As a chemical weapon, mustard gas has been used in several armed conflicts since World War I, including the Iran–Iraq War. Sulfur-based and nitrogen-based mustard agents are regulated under Schedule 1 of the 1993 Chemical Weapons Convention, as substances with few uses other than in chemical warfare. Mustard agents can be deployed by means of artillery shells, aerial bombs, rockets, or by spraying from aircraft.
