title: Fluorescence labelling of pyrimidine nucleobases and their related compounds for high-performance liquid chromatography.
abstract: Fluorescence derivatization of pyrimidine nucleobases and nucleosides with 4-bromomethyl-7-methoxycoumarin(Br-Mmc) was studied. In dimethylsulfoxide(DMSO) containing powdered potassium carbonate, the reaction completed within 5 min at room temperature. The excess Br-Mmc was treated with p-nitrobenzoic acid(NBA) which gave a non-fluorescent compound. For the determination of serum sample, diethylaminoethyl sepharose(DEAE) column was used in a cleanup procedure.
