title: 1H NMR, mass spectroscopic studies and color fastness properties of methyl-4,6-dihydroxy-2-oxo-1-phenyl-5-arylazopyridine-3-carboxylate, part III: new disperse dyes.
abstract: 1H NMR and mass spectroscopic studies of new disperse dyes synthesized from methyl-4,6-dihydroxy-2-oxo-1-phenyl pyridine-3-carboxylate. Application of the dyes on polyester fabric and color fastness properties are also studied. The dyes are also found to possess DPPH free radical scavenging activity.
