Abstract
Disclosed is a composition including flocoumafen and an amount of a configurational stereoisomer of flocoumafen, named enantiomer E4, such that the ratio of this amount to the amount of flocoumafen in the composition is less than 10%, the enantiomer E4 being present with the exclusion of a racemic mixture, the enantiomer E4 having, by chromatographic analysis of flocoumafen, a retention time t4 having a value such that t1<t2<t3<t4; t1, t2 and t3 representing the retention times of the configurational stereoisomers of flocoumafen different from the enantiomer E4, the chromatographic analysis being performed at a temperature of 23.5° C.
