The invention relates to a configuration stereoisomer, said enantiomer E3, of bromadiolone having, by chromatographic analysis of a bromadiolone composition comprising four bromadiolone configuration stereoisomers carried out under the conditions described below, a reaction time of retention t3 of value such that t1 <t2 <t3 <t4; t1, t2 and t4 being the retention times of bromadiolone configuration stereoisomers distinct from said enantiomer E3, said analysis being carried out at a temperature of 27.3 ° C. |
