Synthesis, Characterization of Azo Dyes and their Biological Studies
Authors
Abstract
A series of new azo dyes (2-6) were synthesized by diazotization of 2 – amino, 6 – methyl pyrimidine 4-ol (1) and followed by coupling with different coupling components such as 1-naphthol, 2- naphthol, 6 bromo 2- naphthol, 8-hydroxy quinoline and salicylic acids. The novel azo dyes are also orange-red in color and were characterized by various physico chemical methods like IR, UV-Vis, NMR spectral techniques etc.. The synthesized compounds were screened for their biological activies(antibacterial) and the results are compared with the standards.
