The pyrimidine bases cytosine, uracil and thymine, along with some analogues, are electrophore-labeled either with pentafluorobenzoyl chloride (PFBC), pentafluorophenylsulfonyl chloride (PPSC), or heptafluorobutyric anhydride. Subsequent alkylation is most successful forPFB-cytosine,PFB-cytosine,PPS-uracil, andPPS-thymine. These same alkylated compounds also have the highest aqueous stability and respond most strongly by gas chromatography—electron-capture detection. One of these derivatives, determined to beN4-PFB-1,3-dimethylcytosine by authentic synthesis, and its 5-methyl analgue, can be detected with good precision down to the 100-fg level. Poor reprocucibility is encountered at the 10-fg level.
