Product Description:
Calconcarboxylic acid is widely used as a metallochromic indicator in complexometric titrations, particularly for determining calcium and magnesium ions in water hardness analysis. It forms a distinct color change when bound to these metal ions, making it valuable in analytical chemistry for accurate endpoint detection. Additionally, it is employed in biochemical research for studying metal ion interactions in biological systems. Its stability and sensitivity to specific metal ions make it a reliable tool in both laboratory and industrial settings.
