Abstract:
Disclosed is a configurational stereoisomer, named enantiomer E 3 , of bromadiolone having, by chromatographic analysis of a bromadiolone composition including four configurational stereoisomers of bromadiolone performed under the conditions described hereinbelow, a retention time t 3  having a value such that t 1 <t 2 <t 3 <t 4 ; t 1 , t 2  and t 4  being the retention times of the configurational stereoisomers of bromadiolone different from the enantiomer E 3 , the analysis being performed at a temperature of 27.3° C.

Claim (Index 11):
11 / Chromatographic process for obtaining said enantiomer E 3  according to  claim 1 , in which:\n a high-pressure liquid chromatography column of dimensions 150\u00d72 mm, and containing a chiral stationary phase constituted of particles of cellulose tris(3,5-dimethylphenyl carbamate), is chosen, said particles having a mean size of 3 \u03bcm and having a mean pore size of 1000 \u212b; a mixture formed from acetonitrile (A) and water comprising 0.1% by volume of formic acid (B), with an A/B volume ratio of 80/20, is chosen as liquid mobile phase; the separation is performed at room temperature; a liquid composition containing said enantiomer E 3  dissolved in acetonitrile is introduced into the top of the chromatography column; and then the liquid mobile phase is passed at a flow rate of 0.25 mL/min through the chromatography column after the liquid composition, and a fraction of the mobile phase comprising said enantiomer E 3  is collected at the column outlet, separately from the configurational stereoisomers of bromadiolone different from said enantiomer E 3 , and with a retention time t 3  having a value such that t 1 <t 2 <t 3 <t 4 ; t 1 , t 2  and t 4  being the retention times of each of the configurational stereoisomers of bromadiolone different from said enantiomer E 3 ; and\n the liquid mobile phase of said fraction is removed so as to obtain said enantiomer E 3 .
