General description

Cupferron (Cup) is an ammonium salt of N-nitroso-N-phenylhydroxylamine. It acts as an organic chelation reagent by co-ordinating through the oxygen atoms. Its radiomimetic effect is reported to be affected by the pH and temperature of the treatment solution.

Application


  • A solvothermal route to ZnO and Mn-doped ZnO nanoparticles using the cupferron complex as the precursor.: This research presents a novel method to produce zinc oxide and manganese-doped zinc oxide nanoparticles using cupferron as a precursor, showcasing its application in material synthesis in analytical chemistry (Ghosh et al., 2004).

  • Determination of tellurium in geochemical materials by flameless atomic-absorption spectroscopy.: Demonstrates the role of cupferron in enhancing the analytical methodologies for tellurium determination, underpinning its significance in geochemical studies (Sighinolfi et al., 1979).

  • Extraction of vanadium into isobutyl methyl ketone.: Outlines a method for extracting vanadium using cupferron, which plays a crucial role in the development of methods for the quantitative analysis of vanadium in various samples (Crump-Wiesner and Purdy, 1969).

  • Substituted hydroxylamines as analytical reagents.: Discusses the application of substituted hydroxylamines, including cupferron, as reagents in chemical analysis, illustrating the compound′s adaptability and utility in analytical chemistry (Shendrikar, 1969).
