Herein, napthalen-1-yl-methylene-benzenesulfonohydrazide (NMBSH) molecules were synthesized in a good yield using 1-naphthaldehyde, benzenesulfonyl hydrazide (BSH), and 4-methyl-benzenesulphonylhydrazine (4-MBSH) via an uncomplicated condensation procedure, which were crystallized in EtOH. The NMBSH molecules were characterized using spectroscopic techniques such as H-1-NMR, C-13-NMR, FTIR, and UV-vis spectroscopy. Structures of the NMBSH molecules were established using the single crystal X-ray diffraction method (SCXRDM). The NMBSH molecules were used to detect the metal ion (MI) cerium (Ce2+) using a dependable current-voltage (I-V) progression. A thin layer of NMBSH was deposited onto a flat GCE with a coating binder, nafion (Nf), to modify the sensitive and selective Ce2+ sensor. The methodical parameters, such as sensitivity, LOD, and LOQ, of the proposed sensor (NMBSH/GCE) towards Ce2+ were calculated from the calibration curve (CC) as 632.9 pA M-1 cm(-2), approximate to 96.0 pM, and 320 mM, respectively. This potential NMBSH/GCE sensor was found to be adequate when applied for the selective determination of Ce2+ in spiked ecological samples such as industrial effluent, red sea water, and well water.
