LEWISITE Meaning and
Definition
-
Lewisite is a highly toxic chemical compound that belongs to the group of chemical warfare agents known as vesicants or blistering agents. The term "lewisite" refers specifically to the organic arsenical compound 2-chlorovinyldichloroarsine, represented by the formula C2H2AsCl3. It is named after the American chemist and Nobel laureate, Winford Lee Lewis, who first synthesized it in 1918.
Lewisite is a pale yellow, oily liquid at room temperature and has a strong and distinct odor similar to geraniums. It is sparingly soluble in water but soluble in organic solvents. It is most commonly produced as a mixture with other arsenic-containing compounds, known as "Lewisite mixture," for military purposes.
The substance is highly toxic and poses a severe threat to both human health and the environment. It acts as a potent vesicant by causing painful, blistering burns on contact with the skin, eyes, and mucous membranes. Inhalation or ingestion can also lead to serious respiratory distress, nausea, vomiting, and even death. Its toxic effects can be both immediate and long-lasting.
Due to its extremely hazardous nature, lewisite has been classified as a Schedule 1 substance under the Chemical Weapons Convention, and its production, stockpiling, and use are strictly prohibited. It is primarily used as a reference compound in the development and testing of protective measures against chemical warfare agents.

Etymology of LEWISITE
The word "lewisite" takes its name from American chemist Winford Lee Lewis (1878-1943), who developed the compound in the early 20th century. Lewis was a renowned chemist and a pioneer in the field of chemical warfare. He worked at the United States Bureau of Mines during World War I, where he led a team that discovered and synthesized lewisite. The substance was subsequently named after him in recognition of his contribution to its development.
