Product Description:
Eriochrome blue SE is widely used as a metallochromic indicator in complexometric titrations, particularly for determining metal ions like calcium and magnesium in water hardness analysis. It changes color when it binds to these metal ions, making it a valuable tool in analytical chemistry for precise endpoint detection. Additionally, it is employed in dyeing processes for textiles, where it acts as a mordant dye, forming stable complexes with metal ions to enhance colorfastness. Its ability to selectively interact with specific metals also makes it useful in research and industrial applications for metal ion detection and separation.
