Xylenol Orange Tetrasodium Salt is a water-soluble, metal-chelating dye widely used in analytical chemistry. It is the tetrasodium salt form of Xylenol Orange and exhibits strong color changes upon binding with metal ions, making it useful in various detection methods.
🏭⚗️ Synthesis
Xylenol Orange Tetrasodium Salt is synthesized by neutralizing the acidic form of Xylenol Orange with sodium hydroxide. This reaction converts all acidic protons into sodium salts, resulting in a water-soluble tetrasodium compound.
🧪 Applications
This compound is mainly used as a metal ion indicator in complexometric titrations, especially for detecting iron (Fe³⁺). It is also applied in spectrophotometric assays to measure peroxides and used in biochemical and analytical labs due to its color change upon binding metals.
⚠️ Safety
Xylenol Orange Tetrasodium Salt may irritate the eyes, skin, and respiratory system. It should be handled with gloves and eye protection. Though it is not highly toxic, it can be harmful to aquatic environments and should not be released into drains.
