o -dianisidine chlorosulfonate ( 3,3'-dimethoxybenzidine chlorosulfonate ) is the chlorosulfonic acid salt of o -dianisidine . The substance wasunsuccessfully used as a chemical weapon duringthe First World War .

There is no CAS number for the compound, but it has been given the index number 612-037-00-5 in the European Ordinance on Hazardous Substances.

use

Dianisidine chlorosulfonate was first used in Germany in the Ni-10.5 cm shrapnel grenade of the light field howitzers. The explosive device contained the said dianisidine chlorosulfonate, a precursor from the manufacture of paints. The fine crystalline powder irritates the mucous membranes of the eyes and nose. The first use of these grenades took place on September 27, 1914 on the western front near Neuve-Chapelle. But there was no success. It turned out that the substance had partially decomposed due to the heat generated by the explosive charge when it was fired. Therefore, when used in the field, a sufficient concentration of the active ingredient in the air could not be achieved. More effective alternatives were sought. The xylyl bromide was remembered and the 15 cm 12 T gas explosive grenade was developed from it, which was then used in January 1915 on the Eastern Front near Bolimov . This ammunition did not prove itself either, since the active substance crystallized in the air and therefore an adequate concentration in the air could not be achieved either.
