(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.


an irritant compound derived from the dried ripe seed of Brassica (Sinapis) alba, B. nigra or B. juncea. Contains toxic allyl isothiocyanate in nontoxic glycoside form, though the plant also contains myrosinase, an enzyme that converts the glycoside to the toxic form. Used as a carminative, emetic and counterirritant in poultices.
