2-(9-Carbazole)-ethyl-chloroformate (CEOC), a novel pre-column fluorescence labeling reagent, has been synthesized and applied for the derivatization of phenols. Taken phenol, p-chlorophenol, 2,5-dimethylphenol, 2,4-dichlorophenol and 1,4-dihydroxybenzene as testing standards, the effects of derivatization conditions, such as pH of borate buffer, reaction time and fluorescent tagging reagent concentration,...
2-(9-Carbazole)-ethyl-chloroformate (CEOC), a novel pre-column fluorescence derivatization reagent, has been developed for the analysis of aromatic amines. Taking five monocyclic aromatic amines (o-toluidine, aniline, 3,4-dimethylaniline, N-ethyl-p-toluidine, and p-phenylenediamine) as testing compounds, derivatization conditions such as pH of borate buffer, reaction time and fluorescent tagging reagent...
