Zincon is widely used as a colorimetric reagent for the detection and quantification of metal ions, particularly zinc and copper, in various samples. Its ability to form colored complexes with these metals makes it a valuable tool in analytical chemistry for water quality testing, environmental monitoring, and industrial processes. In biological research, Zincon is employed to study metal ion interactions in cells and tissues, aiding in understanding metal homeostasis and toxicity. Additionally, it is utilized in educational laboratories to demonstrate principles of complexometric titrations and spectrophotometry. Its sensitivity and selectivity make it a practical choice for applications requiring precise metal ion analysis.
