Ethyldichloroarsine, sometimes abbreviated as "ED" and "CY" 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]
