Lewisite: History, Applications & Measurement

Lewisite (L) (A-243) is an organoarsenic compound. It was once manufactured in the United States, Japan, Germany and the Soviet Union for use as a chemical weapon, acting as a vesicant (blister agent) and lung irritant. Although colorless and odorless in its pure form, impure samples of lewisite are a yellow, brown, violet-black, green, or amber oily…
