A new cytidine nucleotide was found in Azotobacter vinelandii strain O. On the basis of chemical analyses, mass spectra, infrared spectra, nuclear magnetic resonance spectra, periodate oxidation studies, and a series of degradation studies followed by comparison with authentic samples, it is proposed that the new compound is cytidine-5'-diphospho-6-deoxy-3-C-methyl-2-O-methyl-4-O-(O-methylglycolyl)-l-aldohexopyranose. The compound is therefore an O-methylglycolic acid ester of cytidine-5'-diphospho-vinelose previously found in the same microorganism.
