Chemical identity and properties

Chloropicrin
Chloropicrin is a C-nitro compound that is nitromethane in which all three hydrogens are replaced by chlorines. It is a severe irritant, and can cause immediate, severe inflammation of the eyes, nose and throat, and significant injuries to the upper and lower respiratory tract. Formerly stockpiled as a chemical warfare agent, it has been widely used in the US as a soil fumigant, particularly for strawberry crops. It is not approved for use within the European Union. It has a role as a nematicide, a fumigant insecticide and an antifungal agrochemical. It is a C-nitro compound, an organochlorine compound and a one-carbon compound. — ChEBI
