Ali Deeb, Salah Shaqra, Taha Abo Elfotoh, Sameh Dief.




Abstract

3-Diazopyrazolo[3,4-c]pyridazine was synthesized and its transformations were investigated. With reactive methylene compound the
corresponding hydrazones were formed. The prepared azo disperse dyes were applied to polyester fabric, and their spectral and color
fastness properties measured.

Key words: 3-diazo-4,5-diphenyl-3H-pyrazolo[3,4-c]pyridazine; active methylenes; color fastness.
