description Product Description
Used primarily as a dye in analytical chemistry for the detection of magnesium ions. It forms a distinct color change, typically a blue or violet hue, when it complexes with magnesium, making it useful in qualitative and quantitative analysis. Additionally, it serves as a pH indicator in certain applications, helping to identify the acidity or alkalinity of solutions. Its sensitivity to magnesium makes it valuable in environmental testing, water quality assessment, and laboratory research.
