Physical description & handling notes

• Chloropicrin appears as a slightly oily colorless to yellow liquid with a strong irritating odor. Noncombustible. Denser than water. Vapors are poisonous by inhalation and irritate eyes, nose, and throat.
• Colorless to faint-yellow, oily liquid with an intensely irritating odor. [pesticide] [NIOSH]
• SLIGHTLY OILY COLOURLESS LIQUID WITH PUNGENT ODOUR.
• Colorless to faintly yellow oily liquid.
• Slightly oily liquid
• Faint yellow liquid.

GHS Hazard Classification

Reported hazard statements	H302, H315, H319, H330, H335, H301, H314, H318

Documented Uses

• Used as a grain, crop, and soil fumigant; also used as an intermediate in organic synthesis and a warning odorant for odorless fumigants and gases; [NIOSH Guidelines for Chemical Hazards]
• When used as a pre-plant soil fumigant in agricultural settings and in greenhouses, chloropicrin is used to control weeds, nematodes, insects, and various soil borne pathogens. In existing orchards chloropicrin is used to treat small areas to control weeds, nematodes, insects, and various soil borne pathogens. Chloropicrin is also used to control internal wood decay caused by fungi and insects in wood poles, timbers, pilings, and glue-laminated beams.
• Disinfecting cereals and grains; in synthesis, especially manufacture of methyl violet; fumigant; soil insecticide; war gas

• Chloropicrin (PS) is used in agriculture as a soil fumigant. It has also been used as a chemical warfare agent (military designation, PS) and a riot control agent. It was used in large quantities during World War I and was stockpiled during World War II. However, it is no longer authorized for military use. Chloropicrin (PS) is an irritant with characteristics of a tear gas. Chloropicrin (PS) has an intensely irritating odor. Inhalation of 1 ppm causes eye irritation and can warn of exposure.
• PREPN: By action of hypochlorites and steam on calcium picrate.
