Compound: 4-Methyl-1,8-naphthyridine, is researched, Molecular C9H8N2, CAS is 1569-17-1, about The ultraviolet absorption spectra of monosubstituted 1,8-naphthyridines [1].
UV absorption spectra of 1,8-naphthyridines were measured in MeOH. The effects of the substituent and its location in the naphthyridine ring on the spectral bands were analyzed. The spectral anal. revealed that 4-hydroxy-, 2-, and 4- mercapto-1,8-naphthyriolines had in MeOH the structures of 1,8-naphthyriolin-4-(1H)-one, 1,8-naphthyridin-2(1H)-thione, and -4(1H)-thione resp.
