Synthesis, Characterization, and Biological Activity of 5-Phenyl-1,3,4-thiadiazole-2-amine Incorporated Azo Dye Derivatives

الملخص EN

5-Phenyl-1,3,4-thiadiazole-2-amine has been synthesized by single step reaction.

A series of heterocyclic azodyes were synthesized by diazotisation of 5-phenyl-1,3,4-thiadiazole-2-amine by nitrosyl sulphuric acid followed by coupling with different coupling compounds such as 8-hydroxyquinoline, 2,6-diaminopyridine, 2-naphthol, N,N-dimethyl aniline, resorcinol, and 4,6-dihydroxypyrimidine.

The dyes were characterized by UV-Vis, IR, 1H-NMR, 13C NMR, and elemental analysis.

The synthesized compounds were also screened for biological activity.
