Nishida, K. published the artcileDyeing properties of disperse dyes derived from substituted 3-aminobenzo[b]thiophenes, Synthetic Route of 67189-92-8, the main research area is benzothiophene azo disperse dye; acetate fiber dye; polyamide fiber dye.
Six disperse azo dyes (I; R = CN, Ac, CO2Et, CO2H; R1 = H, Cl) λ 400-517 nm (EtOH) were prepared by coupling m-MeC6H4N(CH2CH2OH)CH2CH2CN [119-95-9] with diazotized 3-aminobenzo[b]thiophenes and their dyeing properties on acetate and nylon 6 fibers determined Most of the dyes showed good substantivity for both fibers, exhausting well to give bright dyeings of good general fastness; some showed higher lightfastness and brighter colors on acetate than on nylon 6.
Journal of the Society of Dyers and Colourists published new progress about Acetate fibers Role: USES (Uses). 67189-92-8 belongs to class benzothiophene, name is Ethyl 3-amino-4-chlorobenzo[b]thiophene-2-carboxylate, and the molecular formula is C11H10ClNO2S, Synthetic Route of 67189-92-8.
