Ethyldichloroarsine, sometimes abbreviated "ED" and also known as ethyl Dick,^[1] is an organoarsenic compound with the formula CH₃CH₂AsCl₂. This colourless volatile liquid is a highly toxic obsolete vesicant or blister agent that was used during World War I in chemical warfare.^[2] The molecule is pyramidal with the Cl-As-Cl and C-As-Cl angles approaching 90° (see image). Ethyldichloroarsine has high chronic toxicity, similar to lewisite.^[3]
