The present article deals with the synthesis, spectral characterization and antimicrobial activity of phenylazo dyes. All of the synthesized phenylazo dyes were characterized using ATR-FTIR, FT-Raman, 1H NMR, 13C NMR, elemental analysis and mass spectroscopic techniques. Solvent effects on the UV–Vis absorption spectra of these phenylazo dyes were studied. Acid and base effects on the visible absorption maxima of the phenylazo dyes were also reported. The structural and spectroscopic analysis of the molecules were carried out using Density Functional Theory (DFT) employing the standard 6-31G(d) basis set, and the optimized geometries and calculated vibrational frequencies were evaluated via comparison with experimental values. The antimicrobial activity of 4-(substituted phenylazo)-3,5-diacetamido-1H-pyrazoles was reported against bacteria, including B. cereus (RSKK 863), S. aureus (ATCC 259231), M. luteus (NRRL B-4375), E. coli (ATCC 11230) and the yeast C. albicans (ATCC 10239).
