Elution order, specific rotations, recoveries and enantiomeric excess values for the resolved enantiomers of MDPV

Enantiomer	Elution order	${[α]}_{D}^{25^{\circ} C}$ (c)^a	Recovery (%)	ee^b (%)
S-(−)-MDPV	First	−0.23 (10)	91.0	99.1
R-(+)-MDPV	Second	+0.08 (10)	82.6	94.4 (99.6 after reinjection)

^aSpecific rotation in ethanol with a concentration in mg/mL

^b ee enantiomeric excess determinated by chiral liquid chromatography under the conditions described in Fig. 7
