  • When was mustard gas first used?
  • Mustard gas was first used in World War I by the German army against British and Canadian soldiers near Ypres, Belgium, on July 12, 1917. Later also against the French Second Army. Yperite is "a name used by the French, because the compound was first used at Ypres."
  • What is the chemical structure of mustard gas?
  • Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Mustard gas or sulfur mustard are names commonly used for the organosulfur chemical compound bis (2-chloroethyl) sulfide, which has the chemical structure S (CH 2 CH 2 Cl) 2, as well as other species.
  • How effective was mustard agent?
  • Exposure to mustard agent was lethal in about 1% of cases. Its effectiveness was as an incapacitating agent. The early countermeasures against mustard agent were relatively ineffective, since a soldier wearing a gas mask was not protected against absorbing it through his skin and being blistered.
  • Who invented mustard chemistry?
  • In 1860, the British scientist Frederick Guthrie synthesized and characterized the mustard agent compound and noted its irritating properties, especially in tasting. Also in 1860, chemist Albert Niemann, known as a pioneer in cocaine chemistry, repeated the reaction, and recorded blister-forming properties.
