Used primarily in analytical chemistry as a reagent for the detection and determination of metal ions, particularly in complexometric titrations. It functions as a chelating agent due to its ability to form stable coordination compounds with certain transition metals. Its oxime group enhances selectivity toward metals like nickel and copper, making it useful in qualitative inorganic analysis. Additionally, it has been explored in the synthesis of pharmaceutical intermediates, where its structural properties contribute to the development of bioactive molecules. Limited solubility in water but moderate solubility in organic solvents allows for use in non-aqueous reaction systems.
