Novel heterocyclic derivatives of 1-aryl(hetaryl)-3-methyl-4-azopyrazolone-5 and its metal complexes were synthesized. Their color properties were evaluated spectrophotometrically. The ability to use the synthesized compounds as dispersed yellow-to-red dyes for polyamide fibers was demonstrated. © 2016 Springer Science+Business Media New York
