| Abstract | ||
| Disperse dyes are considered important dyes in the dye industry and their use has increased significantly in recent years. Therefore, our goal is to prepare a new series of these dyes and use them in dyeing polyester fabrics, and also to demonstrate the added value of these dyes, as they have activity against many microbes. Making a number of disperse dyes based on pyrazolopyrimidinones is the aim of this investigation. Arylhydrazonopyrazolones 2a-f [3-amino-4-(2-(4-substitutedphenyl)hydrazono)-1H-pyrazol-5(4H)-one] and enaminone 1 [(E)-1-(4-bromophenyl)-3-(dimethylamino)prop-2-en-1-one] reacted in an acidic environment to create these dyes. FTIR, mass, UV, NMR, and elemental studies were used to determine their structures. The fastness characteristics of these disperse dyes were evaluated after they were applied to polyester fabrics. The potential, biological activities of these noel disperse dyes against different cultures of bacteria were also carried out. | ||
