Abstract: Various monoazo reactive dyes have been synthesized by diazotized 3- (4- (4-amino-3-nitrobenzyl) -2-nitrophenyl) -2-phenylquinazolin-4 (3H) -one and coupling with various 2- (4-aminophenylsulphonyl) ethyl hydrogen sulfato cyanurated coupling components such as H-acid, gamma acid, J-acid, N-Methyl J-acid, N-Phenyl J-acid, S-acid, Naphthionic acid, Peri acid, Bronner acid, Tobias acid, K-acid and Koch acid. They are characterised by elemental analysis, IR and PMR spectra. Dyeing properties of these dyes on silk, wool and cotton have been assessed. The dyed fibres showed moderate to very good fastness properties.
