TI  - Development of sensitive high-performance liquid chromatography with fluorescence 
      detection using 4-(4,5-diphenyl-1H-imidazol-2-yl)-benzoyl chloride as a labeling 
      reagent for determination of bisphenol A in plasma samples.

AB  - A sensitive HPLC method for determination of bisphenol A (BPA) in plasma samples 
      using 4-(4,5-diphenyl-1H-imidazol2-yl)benzoyl chloride (DIB-Cl) as a fluorescence 
      labeling reagent was developed. The fluorescence labeling reaction was completed 
      within 10 min at room temperature. DIB-Cl reacts with the phenolic hydroxyl group 
      of BPA in the presence of triethylamine (TEA). The DIB-Cl derivative of BPA 
      (DIB-BPA) was separated within 30 min with an ODS column using acetonitrile-water 
      (90:10, v/v) as the isocratic eluent. Calibration graphs were linear over the 
      range of 1.0-100 ng/ml (r=0.999). The detection limit of DIB-BPA was 0.05 ng/ml 
      (2.5 pg) at a signal-to-noise ratio of 3. The relative standard deviations (RSDs) 
      of the method for between-run were 1.0-5.0%. The analytical recoveries of known 
      amounts (1.0 and 100 ng/ml) of BPA-spiked rabbit plasma were around 95%.
