Brodifacoum is very similar to Difenacoum in its chemical structure and anticoagulant effect (they are both 4- hydroxycoumarin derivatives). Brodifacoum is a weak acid which does not readily form water-soluble salts. It does not lose activity after 30 days in direct sunlight. Commercial formulations are stable at least for two years if protected from extreme temperatures and sunlight. The container should be kept closed to maintain activity of formulation (as a bait). The modern 2nd generation anticoagulant rodenticides such as Brodifacoum have proven severe secondary poisoning properties and have been held responsible for the deaths of many birds of prey, particularly rare Red Kites and Buzzards that habitually feed off dead bodies.
