ABSTRACT

In this work, four azo dyes were synthesized by the diazotization process of four aromatic amines using NaNO2 and HCl, and coupling of these diazonium salts with Resorcinol. The synthesis of azo dyes has been confirmed by FT-IR and H1 NMR spectral data, and their antimicrobial activities have been tested using the disk diffusion method against four different bacteria. These newly synthesized azo dyes are found to have good antimicrobial activity and synthesized in good yield.

Keywords: Azo dyes, Resorcinol, antimicrobial activity.
