1H-pyrazolo[3,4-b]quinolin-3-amine derivatives have been synthesized by the reaction between substituted phenyl pyrazolones and 3-amino-1H-pyrazolo [3,4-b] quinoline. The novel compound structures have been established on the basis of their substituted phenyl pyrazolones derivatives. All the azo compounds were characterized by their percentage yield, melting point, elemental analysis, UV visible spectra, IR spectra, NMR spectra and dyeing performance on nylon, wool, silk and polyester fibers. All the synthesized dyes gave moderate to excellent fastness properties on each fiber.
