o-Cresolphthalein Complexone, also known as cresolpthalein complexone, is a chelating agent and an organic compound that is commonly used in analytical chemistry for the complexometric determination of metal ions, particularly calcium and magnesium. It is a colorimetric reagent that forms stable complexes with metal ions, and the resulting color change is used to indicate the endpoint of the titration. o-Cresolphthalein Complexone is known for its high selectivity towards calcium and magnesium ions, making it a valuable tool in the quantitative analysis of these metal ions in various samples, including water, biological fluids, and pharmaceutical formulations. Additionally, it is utilized in complexometric titrations and spectrophotometric methods for the determination of calcium and magnesium content in a wide range of applications.
