A kinetic study based on spectrophotometric and titrimetric techniques has been carried out for the formation of Rubazoic acid (4E)-4-[(5-hydroxy-3-methyl-1-phenyl-4,5-dihydro-1H-pyrazol-4-yl)imino]-5-methyl-2-phenyl-2,4 dihydro-3H-pyrazol-3-one from 4-amino-1(4-sulphophenyl) 3-methyl-2-pyrazolin-5-one. Physicochemical factors like effect of time, pH, aeration and temperature on its formation have been investigated in detail. Elemental analysis, UV-Visible spectral study, FTIR spectral study, 1H-NMR and 13C-NMR spectral study was employed for understanding the reaction path way for the formation of rubazoic acid.
