Quinoline incorporating pyrimidine heterocyclic azo dye derivatives: Synthesis, characterization and applications (vol 62, pg 380, 2023)

In the present study, novel quinoline substituted pyrimidine heterocyclic azo dye derivatives (IVa-x) have been synthesized. All the prepared compounds have been characterized by several spectroscopic analyses and evaluated for in vitro antimicrobial activity. Furthermore, the dyeing performances of all the compounds have been estimated on cotton and silk fabrics. Colour and rubbing fastness properties of all the dyed fabrics have been examined by referencing to standard gray scale. These newly synthesized azo dyes exhibit various hues with good to excellent fastness properties. Out of all the phenol derivatives, Naphthol substituted compounds have come out as remarkably active antimicrobial scaffolds with excellent dye characteristics.
