Salvador, Maria A. published the artcileNear-infrared absorbing delocalized cationic azo dyes, Application of 1-Ethyl-2-methylquinolin-1-ium iodide, the publication is Dyes and Pigments (2009), 82(2), 118-123, database is CAplus.
Novel, delocalized, cationic azo dyes derived from benzothiazole, benzoselenazole, indole and quinoline, displaying strong absorption around 700-800 nm, have been prepared in moderate to good yields. The synthesis involved the Knoevenagel condensation of an intermediate azo compound, possessing a 4-chloro-5-formylthiazole moiety, with methylenic bases generated in situ from benzoazolium and quinolinium salts.
Dyes and Pigments 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.
