phos·gene (CG),

Carbonyl chloride; a colorless liquid below 8.2°C, but an extremely poisonous gas at ordinary temperatures; it is an insidious gas, given that it is not immediately irritating, even when fatal concentrations are inhaled; more than 80% of World War I's chemical agent fatalities were caused by phosgene.
