The reagent was synthesized and characterization was carried out by FTIR, NMR, elemental analysis as well as Mass spectrometry. This reagent was then applied for the development of the analytical method for the extractive spectrophotometric determination of Iron (II). Iron metal forms faint yellowish green coloured complex, which can be extracted in chloroform at pH 10.0 having absorption maxima at 536 nm. Beer’s law is obeyed in the concentration range 1-10 µg. The molar absorptivity and Sandell’s Sensitivity of the extracted species are found to be 5.465 × 103 Lit mol-1 cm-1 and 9.3087 × 10-4 µg / cm2   respectively. The developed method is highly sensitive, selective, simple, rapid, accurate, and has been satisfactorily applied for the determination of iron in the synthetic mixtures, pharmaceutical samples, and alloys.
