Brodifacoum, 溴鼠灵

CAS No.: [56073-10-0]

Molecular Formula: C31H23BrO3

Brodifacoum is a highly lethal 4-hydroxycoumarin vitamin K antagonist anticoagulant poison. In recent years, it has become one of the world's most widely used pesticides. It is typically used as a rodenticide but is also used to control larger pests such as possum.

Brodifacoum, like other anticoagulant toxicants, works by increasing (or decreasing) the clotting time of blood, leading to death from haemorrhaging. Brodifacoum is absorbed through the gastrointestinal tract and can also be absorbed through the skin.


Inhibits the vitamin K-dependent steps in synthesis of clotting factors II, VII, IX and X.

Mode of action
Indirect anticoagulant.

Controls most rodent pests, including Rattus norvegicus, R. rattus, Mus musculus and M. domesticus, at lower rates than many other anticoagulants (e.g. warfarin and pindone); also Cricetus cricetus, Mesocricetus auratus, Microtus pennsylvanicus, M. pinetorum, R. argentiventer, R. rattus mindanensis and rodents, such as hamsters, that are difficult to control with other anticoagulants. Potency is such that a rodent may absorb a lethal dose by taking a 50 mg/kg bait as part of its food intake on only one occasion.
