Abstract
Abstract A method is presented for the simultaneous determination of Triclocarban (N-(4-chlorophenyl)-N'-(3,4-dichlorophenyl)urea, [101-20-2] Cloflucarban (N-(4-chlorophenyl)-N'-[4-chloro-3-(trifluoromethyl)phenyl]urea, [369-77-7]) and the related anilines, 4-chloroaniline, 3,4-dichloroaniline and 4-chloro-3-trifluoromethyl aniline.∗ Temperature programmed gas chromatography, after preparing trimethylsilyl derivatives is employed, using MSTFA (N-methyl-N-trimethyl-silyl trifluoroacetamide) as the derivatizing agent and a column with Dexsil 400 as the stationary phase. On a glass column quantitative results are obtained and linear calibration plots are obtained using phenanthrene as an internal standard, for 20-400 ng Triclocarban with a flame-ionization detector. Well-resolved gas chromatograms are obtained for the several compounds.
