This chemical is primarily used as a chromogenic reagent in colorimetric analysis for the detection and quantification of cobalt (Co) and cadmium (Cd) ions. It forms colored complexes with these metal ions, enabling their identification and measurement through spectrophotometric techniques. The reagent is particularly valued for its sensitivity and selectivity in analytical chemistry, making it a useful tool in environmental monitoring, industrial quality control, and research laboratories. Its application ensures accurate determination of trace metal concentrations in various samples, including water, soil, and biological materials.
