Alizarin Yellow R sodium salt (CAS 1718-34-9)

Alizarin Yellow R sodium salt holds a significant position as an azo dye leveraged in numerous scientific applications. This water-dissolvable dye exhibits a vivid yellow hue and is frequently utilized as a chromogenic reagent in biochemical tests. Additionally, Alizarin Yellow R sodium salt serves as a fluorescent indicator in a range of biochemical assays and as a reagent for identifying metal ions. This compound offers many benefits, making it an essential tool for investigating biochemical and physiological processes. Most notably, Alizarin Yellow R sodium salt is employed as a chromogenic reagent for protein detection, finding use in immunoassays, enzyme assays, and other biochemical tests. Furthermore, it′s used as a fluorescent indicator in various biochemical assays and as a reagent for metal ion detection. It′s also been used for detecting nitrate ions in water. As a chromogenic reagent, Alizarin Yellow R sodium salt changes color when it interacts with a target molecule. This color change occurs when the azo group in the molecule becomes cleaved after exposure to a target molecule, releasing the yellow-colored 4-nitrobenzene group.
