A series of heterocyclic monoazo quinazolinone based heterocyclic monoazo dyes derived by the diazotization of 3-(4-aminophenyl)-2-phenylquinazolin-4(3H)-one with various Ph pyrazolones based coupling components has been studied. These dyes give mostly yellow shades. All the heterocyclic monoazo dyes have been characterized by their % yield, UV-VIS spectroscopy, IR spectroscopy, 1H NMR spectroscopy, and dyeing performance on silk, wool, nylon, and polyester fibers. The percentage dye bath exhaustion on different fibers is found to be reasonably good and acceptable. The dyed fibers show moderate to very good light fastness and good to excellent washing and rub fastness properties. Spectral properties and colorimetric data (L*, a*, b*, C*, H*, K/S) have also been investigated.
