A new azo reagent, 2-[4-antipyrine azo]-5-methylphenol (A.P.A.M.P.), was synthesized and structurally confirmed using FTIR, UV-Vis and 1H-NMR spectroscopy. The reagent was employed for the cloud point extraction (CPE) and spectrophotometric determination of Cd(II) based on the formation of a stable metal-ligand complex. Experimental variables affecting extraction efficiency were systematically optimized to establish reliable operating conditions. The proposed method exhibited good sensitivity, precision and enrichment capability and its analytical performance was evaluated through comparison with flame atomic absorption spectrometry (FAAS), showing satisfactory agreement. The procedure demonstrates simplicity, low reagent consumption and compatibility with green analytical principles, making it suitable for the determination of cadmium in environmental and biological samples.
