Cellulose-tris (3,5-dimethylphenylcarbamate; CDMPC) was synthesized and coated on aminopropylsilica to prepare chiral stationary phase (CSP). Normal-phase high-performance liquid chromatography (HPLC) methods for the resolutions of five chiral triazole pesticides, diniconazole, tebuconazole, hexaconazole, triadimefon and flutriafol, on the CSP were developed. Several operating parameters such as mobile phase composition, modifier and column temperature were studied for the optimization of the resolutions. Better separations were achieved using 2% iso-butanol for diniconazole, 2% ethanol for tebuconazole, 2% iso-propanol for hexaconazole, 1% n-butanol for triadimefon and 2% n-propanol for flutriafol as modifiers in n-hexane at 0 degrees C with the resolution factors (Rs) of 1.62, 1.66, 2.46, 1.68 and 1.98, respectively. Low temperature was better for the resolutions. Validation of the methods included linearity and precision.
