Ethyldichloroarsine, sometimes abbreviated "ED", is an organoarsenic compound with the formula CH3CH2AsCl2. This colourless volatile liquid is a highly toxic vesicant or blister agent that was used in chemical warfare. The molecule is pyramidal with the Cl-As-Cl and C-As-Cl angles approaching 90° (see image). It is closely related to methyldichloroarsine, which was also used in warfare.
