Koraiem, Ahmed I. M. published the artcileOxonium Salts in the Synthesis and Spectral Behavior of Pyrano(pyrylium)-mono methine Cyanine Dyes, Application of 1-Ethyl-2-methylquinolin-1-ium iodide, the publication is Journal of Heterocyclic Chemistry (2019), 56(6), 1722-1732, database is CAplus.
Pyrano- and pyrylium mono-8[4(1)] and/or 5(6)-[2(4)]methine cyanine dyes (6a-k, 7a-f) were synthesized based on acyclic heterocyclic Schiff bases of pyrolo[3,2-d]pyrazole[oxazole(imidazol-6-one)]-1-ium iodide salts, 5-acetyl-N-aryl[pyrazolinyl(pyridinyl)]pyrolo-[5,4-d]pyrazolin-iodide salts, and/or (anhydro bases) precursors (1a-i, 2a-I, 3a-i, 4a-i, and 5A,Ba-i). The structure of pyrylium-9-chloride and/or iodide and their pyrano(pyrylium)-mono-8[4(1)] and 5(6)[2(4)]methine cyanine dyes was identified by elemental and spectral data. The absorption spectra of some selected dyes were investigated in 95% EtOH, polar (nonpolar) organic solvents and in universal buffer solutions to investigate the optimal conditions for the application of such dyes as photosensitizers.
Journal of Heterocyclic 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, Application of 1-Ethyl-2-methylquinolin-1-ium iodide.
