Abu El-Hamd, R. M. published the artcileSynthesis, visible spectral studies and biological activity of some new heterocyclic quinone trimethine and merocyanine dyes, Synthetic Route of 606-55-3, the publication is Indian Journal of Heterocyclic Chemistry (1996), 5(4), 305-310, database is CAplus.
New asym. cyanine dyes (I; A = α-picolinyl, quinaldinyl, γ-picolinyl; Z = S, O; II; A = as above; III; R = COMe, CO2Et; and IV) incorporating naphthoquinone in conjunction with thiazole/oxazole and/or oxadiazine moieties were prepared Mol. complex formation with ethanol was verified by mixed solvent studies. The variation of absorbance with pH was utilized for the determination of the pKa value for a selected dye. Bactericidal and fungicidal activity of selected cyanines were determined
Indian 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, Synthetic Route of 606-55-3.
