Gomaa, Maha Mobaruk published the artcileBenzo[g]quinoline heterocyclic derivative as a typical precursor in the synthesis of new class of cyanine-like dyes, Computed Properties of 606-55-3, the publication is European Journal of Chemistry (2012), 3(4), 461-467, database is CAplus.
New unsym. cyanine-like dyes have been synthesized including monomethine, dimethine, and tetramethine types, based on a 3-cyanobenzo[g]quinoline-5,10-dione derivative The new compounds were identified by elemental anal. and IR and 1H NMR spectra. The UV-visible absorption spectra of the dyes are also reported.
European Journal of Chemistry published new progress about 606-55-3. 606-55-3 belongs to iodides-buliding-blocks, auxiliary class Quinoline,Salt, name is 1-Ethyl-2-methylquinolin-1-ium iodide, and the molecular formula is C12H14IN, Computed Properties of 606-55-3.
