Adamsite is a chemical compound with the formula C6H5AsCl2. It is a synthetic organic compound that is classified as a vesicant, meaning it can cause blistering of the skin and mucous membranes upon contact. Adamsite was used as a chemical warfare agent during World War I and World War II, primarily for its irritant and incapacitating effects. It is a yellow to orange powder that is typically dispersed as an aerosol. Adamsite is considered a non-lethal chemical weapon, but can still cause significant injury and discomfort to exposed individuals.
