Phosgene oxime

Phosgene oxime, also called dichloroformoxime or CX, is a chemical weapon, and a nettle agent that damages skin and other body parts. It was first made in the year 1929. When it is solid, it has no color. When it is liquid, it is yellow-brown. It has a strong, very bad odor. The chemical formula phosgene oxime is CCl2NOH.
This chemical has no real use, so accidental exposure is does not happen often. Exposure to CX is almost certainly the result of its use as a weapon.
