Synthesis, Characterization and Antibacterial Screening of Azo Compounds Containing Vanillin Moiety

In this study, a series of azo compounds were synthesized in excellent yields via the diazotization of different aromatic amines followed by coupling with vanillin. These compounds were characterized by elemental analysis, IR, 1HNMR spectral techniques. The synthesized compounds have been tested in vitro against human pathogens in order to assess their antibacterial properties using disk diffusion method. The compounds analysed for its antibacterial action showed inhibitory effect at all concentrations against all the test pathogens.
