sul·fur mustard(sŭl'fŭr mŭs'tărd)
A vesicating chemical-warfare agent used extensively in World War I (1914-1918) and thereafter and sometimes called "mustard gas," a misnomer because it does not boil until 217°C (423°F). The NATO code for the impure sulfur mustard prepared by the Löwenstein process used in World War I is H; the NATO code for neat, or distilled, sulfur mustard is HD.
