Chlorophacinone Chemical Properties,Uses,Production
Description
Chlorophacinone is produced by condensation of 1-
phenyl-1-(4-chlorophenyl) acetone with dimethyl phthalate
in the presence of sodium methoxide (31).
This compound was introduced in 1961 and is now
widely used in Europe, the United States, and elsewhere.
It is used in baits against norway rats at a concentration
of 0.005–0.01%. Bait containing 0.025% chlorophacinone
gave a complete kill of house mice after a 7-d feeding
period but, in other tests, survivors were recorded following
10 and 21 days of feeding (5). Chlorophacinone acts as
an uncoupler of oxidative phosphorylation as well as an
anticoagulant (32), which is unusual among this group of
compounds.
Chemical Properties
Chlorophacinone is a highly toxic crystalline solid.
Uses
Chlorophacinone (CPN) is an anticoagulant rodenticide widely used to control rodent infestations.
General Description
Crystals. Commercially available as oil concentrate and as dust concentrate. Used as an anticoagulant rodenticide. Chronic acting, multiple dose rodenticide.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Fire may produce irritating or poisonous gases.
Health Hazard
Chlorphacinon is highly toxic orally and by skin absorption. The probable oral lethal dose for humans is less than 5 mg/kg to 50 mg/kg, or between a taste (less than 7 drops) and 1 teaspoonful for a 150 lb. (70 kg) person.
Fire Hazard
(Non-Specific -- Coumarin Derivative Pesticide, Solid, n.o.s.) Fire may produce irriating or poisonous gases. Runoff from fire control water may give off poisonous gases. Runoff from fire control or dilution water may cause pollution. When heated Chlorphacinon emits toxic fumes of chlorides.
Agricultural Uses
Rodenticide: This material is an anticoagulant rodenticide used around livestock and also on crops such as artichokes. Some brands are labeled for use indoors and outdoors for the control of mice, rats, moles, muskrats, voles and vampire bats. Not approved for use in EU countries. Registered for use in the U.S. There are 24 global suppliers.

Potential Exposure
Agricultural Chemical. This material is an anticoagulant rodenticide. A potential danger to those involved in its manufacture, formulation, and application are at risk.
