Koraiem, A. I. M. published the artcileSome new nitrogen bridgehead heterocyclic cyanine dyes, Safety of 1-Ethyl-2-methylquinolin-1-ium iodide, the publication is Chemical Papers (2000), 54(2), 78-86, database is CAplus.
New monomethine, trimethine, and azomethine cyanine dyes of pyrazolo[4′,5′:5,6](pyrazinio/1,4-oxazinio)[2,3,4-i,j]quinolin-11-ium bromides were prepared These cyanines were identified by elemental and spectral analyses. The visible absorption spectra of some selected dyes were investigated in single and mixed solvents, and also in aqueous buffer solutions The spectral shifts are discussed in relation to mol. structure and in terms of medium effects. Mol. complex formation with DMF was verified through mixed-solvent studies.
Chemical Papers 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, Safety of 1-Ethyl-2-methylquinolin-1-ium iodide.
