Chemical compound

Difenacoum is a coumarin derivative. It has anticoagulant effects and is used as a rodenticide.

Uses

Difenacoum is sold as blue-green pellets intended to be ingested by pests such as rats and mice.

Safety and toxicity

Because other species of mammals and birds may prey upon affected rodents, there is a risk of secondary or tertiary exposure. Using radiolabled isotopes, difenacoum (and/or its metabolites) has been shown to be distributed across many organ tissues upon oral ingestion, with the highest concentrations occurring in the liver and pancreas.

Difenacoum has been shown to be highly toxic to some species of freshwater fish and green algae despite the fact that difenacoum is weakly soluble in aqueous solutions.
