The polarographic behavior of 1‐[2‐phenyl‐2‐(hydroxyimino)ethyl]‐6‐methylquinolinium chloride has been investigated. The pH of the Britton‐Robinson buffer, used as supporting electrolyte, influences the position of the half‐wave potential which shifts towards more negative values with increasing pH. Well defined, diffusively controlled cathodic waves were observed in acid medium for the overall irreversible reduction of the azomethine group to a primary amino group. A single four‐electron reduction is obtained and a mechanism has been proposed for the reduction. The ratio id/c remains constant and allows a rapid and reproducible determination of the compound (CV = 0.54–2.10 %).
