    Abstract

    2,3,6-Tris(phenylcarbamoyl)-β-cyclodextrin-6-methacrylate was prepared and used as a functional monomer for the preparation of new β-cyclodextrin (β-CD) functionalized polymer monoliths. The polymer monoliths were prepared via the copolymerization of β-CD methacrylate and ethylene glycol dimethacrylate in different ratios in situ in fused silica capillary (internal diameter 150. μm). The effect of functional monomer/cross linker concentration on the chiral separation of different classes of pharmaceuticals namely; α- and β-blockers, antiinflammatory drugs, antifungal drugs, dopamine antagonists, norepinephrine-dopamine reuptake inhibitors, catecholamines, sedative hypnotics, diuretics, antihistaminics, anticancer drugs and antiarrhythmic drugs was investigated. Baseline separation was achieved for propranolol, ifosfamide, alprenolol, tertalol, 1-indanol, tebuconazole, o-methoxymandelic acid, celiprolol and cizolertine under reversed phase conditions with mobile phase composed of methanol and water, using nano liquid chromatography. The method provides more economical analysis under environmentally benign conditions. The prepared capillary columns showed good mechanical stability and good repeatability (run-to run and batch-to batch).
