Coumatetralyl *7%TC
Rodenticide
IUPAC name[hide](RS)**-Hydroxy- *-(1,2,3,*-
tetrahydronaphthalen- *-yl)- 4H- chromen- *-one
CAS number ********3
Coumatetralyl is an anticoagulant of the warfarin type. Symptoms of overexposure
relate to failure of the blood
clotting mechanism and include bleeding gums and failure of
blood clotting after skin wounds. After one exposure the
toxicity of coumatetralyl is
relatively low, however if overexposure continues for several days
the product becomes more toxic. The product must therefore be
constantly present in the bloodstream for more than 1 to 2 days in
order to be highly toxic. A single exposure, even though relatively
large, may not produce toxic symptoms as the compound is quite
rapidly metabolised. Chronic
animal studies show no evidence of carcinogenic or teratogenic effects.
