Synthesis and application of novel heterocyclic dyes based on 11-Amino-3-Bromo-13H-acenaphtho[1,2-e]pyridazino[3,2-b]-quinazoline-13-one

Article abstract of DOI:10.1515/HC.2001.7.6.599

Synthesized a new fused heterocyclic compound, 11-Amino-3-Bromo-13H-acenaphtho[1,2-e]pyridazino[3,2-b]-quinazoline-13-one and is used to synthesize a novel series of heterocyclic mono azo dyes by coupling with various naphthols. All the dyes were characterized by their percentage yield, melting point, UV-visible spectroscopy, elemental analysis, infrared spectroscopy and dyeing performance on nylon 66 and polyester fibres. The percentage dye bath exhaustion on different fibres has been found to be reasonably good and acceptable. The dyed fibres showed fair to fairly good fastness to light and very good to excellent fastness to washing, rubbing, perspiration and sublimation.
