Bis(cyclohexanone)oxalyldihydrazone is primarily used for the spectrophotometric determination of copper(II) ions, forming a stable red-colored complex that allows for sensitive quantification. It also serves as a ligand in the synthesis of coordination compounds with various metals, including nickel and other heavy metals, for analytical and catalytic applications. Additionally, it is employed in the synthesis of hydrazine derivatives and related compounds, potentially as intermediates for catalysts or specialty chemicals in the chemical industry.
