description Product Description
Xylenol Orange tetrasodium salt is widely used as a metallochromic indicator in analytical chemistry, particularly in complexometric titrations. It is effective in detecting metal ions such as iron, aluminum, and zinc due to its ability to form colored complexes with these ions, making it valuable for endpoint determination in titrations. Additionally, it is employed in spectrophotometric analysis for quantifying metal concentrations in various samples, including environmental and biological matrices. Its water solubility and stability in aqueous solutions enhance its utility in laboratory settings.
