Abd El-Aal, R. M. published the artcileSynthesis and solvatochromic behavior of new asymmetrical mono-(tri)-methine cyanine dyes, Synthetic Route of 606-55-3, the publication is Proceedings – Indian Academy of Sciences, Chemical Sciences (1998), 110(4), 433-444, database is CAplus.
6-Amino-5-cyano-3-methyl-1,4-diarylpyrano[2,3-c]pyrazole cationic derivatives were prepared via the interaction of α,β-unsaturated nitriles with 3-methyl-1-phenyl-5-pyrazolone as starting materials in the synthesis of new asym. mono-(tri)-methine cyanine dyes. The new cyanines were characterized by elemental anal. and IR and 1H-NMR spectral data. The visible absorption spectra of some selected dyes were investigated in pure and mixed solvents as well as in aqueous buffer solutions
