Used primarily in analytical chemistry as a reagent for the detection and determination of various metal ions, particularly copper and nickel. It forms colored complexes with these metals, enabling their identification and quantification in samples. Additionally, it finds application in the synthesis of other organometallic compounds and as a catalyst in certain organic reactions. Its use extends to the field of materials science, where it contributes to the development of thin films and nanoparticles with specific optical and electronic properties.
