Coumarin-based anticoagulant rodenticide, very palatable for rodents as well as highly efficient. It controls rats and mice, including rodents resistant to first-generation anticoagulants.


Common name: bromadiolone (BSI, E-ISO, F-ISO); broprodifacoum
IUPAC: 3-[3-[4-(4-bromophenyl)phenyl]-3-hydroxy-1-phenylpropyl]-2-hydroxychromen-4-one
CAS Number: 28772-56-7


It is characterized by being attractive to rodents. A single ingestion of 50 mg/kg is enough to kill Rattus norvegicus and Rattus rattus within 5 days, which does not arouse suspicion in the murine population. It blocks blood coagulation and prothrombin formation. It is effective against warfarin- and coumatetralyl-resistant rats and mice. It is a non-specific poison but, because of very low active substance concentration in baits, risk of accidental poisoning for non-targeted rodent species, including humans, is very low.
