Zincon is widely used as a chemical indicator in analytical chemistry, particularly for the detection and quantification of metal ions. It forms colored complexes with metals like zinc, copper, and nickel, making it valuable in spectrophotometric analysis. In water quality testing, zincon is employed to measure trace amounts of zinc and copper, which are critical for monitoring environmental pollution. It is also utilized in biological research to study metal ion interactions in enzymes and proteins. Additionally, zincon serves as a reagent in educational laboratories for teaching students about complexometric titrations and metal ion analysis. Its sensitivity and specificity make it a reliable tool in both industrial and academic settings.
