Lewisite, also known as L-1 and arsine oil, is a chemical compound with the formula C2H2AsCl3.  > Lewisite (L) (A-243) is an organoarsenic compound. It was once manufactured in the U.S., Japan, Germany and the Soviet Union for use as a chemical weapon, acting as a vesicant (blister agent) and lung irritant. Although the substance is colorless and odorless in its pure form, impure samples of lewisite are a yellow, brown, violet-black, green, or amber oily liquid with a distinctive odor that has been described as similar to geraniums. > > Lewisite is named after the US chemist and soldier Winford Lee Lewis (1878–1943). Apart from its use as a weapon of war, the compound is useless; a chemist from the United States Army's chemical warfare laboratories said that "no one has ever found any use for the compound".[^1] [^1]: Overview of Lewisite pulled from **[Wikipedia](https://en.wikipedia.org/wiki/Lewisite)** on [[06-09-2024]]. %%Footer Starts Here%% --- <center><img src="https://archive.is/do5ay/df25cfff93575f174c387ac9f4c64744da0fadb9.png" alt="Keep digging!" height="100px"></center> --- ### Tags #ChemicalWarfare ### Linked Pages & Footnotes
