The first method on the oxidative coupling Amoxixilin reaction with 2,4- dinitrophenyl hydrazine and Sodium Iodate diluted to produce a soluble red-Orange dye product was devised to estimate the Amoxicillin in bulk and pharmaceutical preparation. The concentration range is between 1 and 50 g/mL. Beer's law is met by the product in terms. With a molar absorptivity of 6.2×103L.mol-1.cm-1 and a correlation coefficient of 0.9995, Sandell's sensitivity is 0.059g.cm-2 at 475 nm. A second technique for determining a trace amount in an aqueous solution product is called cloud point extraction (CPE), and it is based on measurements made with a UV-visible spectrophotometer at a wavelength of 480 nm. The correlation coefficient was 0.9996 and the Beer's law concentration range was 0.25–6 g/mL The molar absorptivity was 103623.79 L.mol-1.cm-1. Pre-concentration 25, detection of limit 0.023 µg/mL. The distribution coefficient (D) was 158.6, and enrichment factor was 28.35. The last method is flow injection analysis, which is straightforward to estimate. The Beer's law concentration range was 2-150 µg / mL, Sandell's sensitivity is 0.13 µg.cm-2 at 475 nm, with a molar absorptivity of 2.8×103 L.mol-1.cm-1 and correlation coefficient was 0.9996, it is successfully used for drug estimation. Qualities in a straightforward situation or pharmacological formulations.
