• Roseoflavin (I) is identified as 7-methyl-8-dimethylamino-10-(1′-D-ribityl)-isoalloxazine (IX) by comparing I with four diastereoisomers of 7-methyl-8-dimethylamino-10-D-<I>n</I>-pentitylisoalloxazine, which were synthesized from 2-dimethylamino-4-amino-toluene, D-pentoses, and violuric acid. The coincidence of chemical and physical properties—elemental analysis, UV-visible absorption spectrum, melting point, optical rotation, <I>R</I><SUB>f</SUB> value in thin layer chromatography, and NMR spectrum—of free and acetylated I with those of the free and acetylated IX, respectively, verified the identity. Some of the properties of I and acetylated I (p<I>K</I><SUB>a</SUB>, oxidation-reduction, absorption spectra, and extinction coefficients of various ionic species, and photosensitivity) are also described.
