Comparison of the chiral resolution of econazole, miconazole, and sulconazole by HPLC using normal-phase amylose CSPs.


PMID 11569882

Abstract

Resolution of the enantiomers of (+/-)-econazole, (+/-)-miconazole, and (+/-)-sulconazole has been achieved on different normal-phase chiral amylose columns, Chi-ralpak AD, AS, and AR. The mobile phase used was hexane-2-propanol-diethylamine, 400:99:1 (v/v). The flow rates of the mobile phase used were 0.50 and 1.00 mL min(-1). The alpha values for the resolved enantiomers of econazole, miconazole, and sulconazole on the chiral phases were in the range 1.63 to 1.04; the Rs values varied from 5.68 to 0.32.
