Chloropicrin, also known as PS (from Port Sunlight) and nitrochloroform, is a chemical compound currently used as a broad-spectrum antimicrobial, fungicide, herbicide, insecticide, and nematicide. It was used as a poison gas in World War I and the Russian military has been accused of using it in the Russo-Ukrainian War. Its chemical structural formula is Cl₃C−N O₂.
