Phenyl 2-Pyridyl Ketoxime is primarily utilized in analytical chemistry as a chelating agent for the extraction and determination of metal ions. It forms stable complexes with various transition metals, making it valuable in spectrophotometric analysis for quantifying metals like copper, nickel, and cobalt in environmental and industrial samples. Additionally, it is employed in organic synthesis as an intermediate for producing pharmaceuticals and agrochemicals, owing to its ability to participate in reactions that form nitrogen-containing heterocycles. Its role in corrosion inhibition is also notable, where it is used to protect metal surfaces in industrial applications.
