Abstract

The new reagent N-methyl-N-((((4-bromophenyl)diazenyl)thio) carbonothioyl) aniline was made by the reaction of (sodium N-methyl-N-phenyldithiocarbamate)with 4-bromobenzenediazoniume salts. UV-Visible spectroscopy, elemental analysis, Fourier-transform infrared spectroscopy, mass spectroscopy, proton nuclear magnetic resonance spectroscopy, carbon-13 nuclear magnetic resonance spectroscopy, magnetic susceptibility measurements, and conductivity measurements to characterize the prepared compound. Using analytical and spectroscopic data, stoichiometry was calculated, and it was discovered that the complex was 1:2 (metal: ligand). The complexes’ molar conductivity was measured using dimethyl formide, and the results indicated that the produced complex was ionic. Results of elemental analysis and spectrum studies indicate that the compound has a tetrahedral structure. Cloud point extraction was created for the preconcentration and separation of Cr(III) in drug sample measurements utilizing flame atomic absorption and a UV-Visible spectrophotometer at a maximum wavelength is 536 nm. The e ectiveness of cloud point extraction is a ected by pH at 7, 20% triton X-114, interference, and salt out impact with 15 min of incubation time, and 70 Celsius of heating. The calibration curve of Cr(III) was linear in the extent from 0.1–2 ppm with a linearity coefficient is 0.988. The limit of detection and quantification is (0.124 and 0.377 ppm). The new method has been successfully applied to the extraction and assay of the metal ion Cr(III) under three pharmaceutical brands.
