This study describes the new simple and accurate spectrophotometric method for the determination of paracetamol after the formation of azo dye with a new chromogenic reagent 4 [(2-amino-1,3thiazol-4-yl)amino] nitrobenzene to form an orangecoloured product measured at 425 nm.The molecular structure of the newly synthesized compound was confirmed by several spectroscopic techniques such as UV-visibl...
