CAS 1668-00-4: Arsenazo III
Description:Arsenazo III, with the CAS number 1668-00-4, is a synthetic organic compound primarily used as a chelating agent and colorimetric reagent in analytical chemistry. It is particularly effective for the detection and quantification of metal ions, especially those of transition metals, due to its ability to form stable complexes. The compound exhibits a distinctive color change upon binding with specific metal ions, making it useful in various analytical applications, including spectrophotometry. Arsenazo III is characterized by its azo dye structure, which contributes to its chromogenic properties. It is soluble in water and exhibits stability under a range of pH conditions, although its performance can be influenced by the presence of competing ions. Safety considerations are important when handling Arsenazo III, as it contains arsenic, which is toxic and poses health risks. Proper laboratory protocols should be followed to mitigate exposure. Overall, Arsenazo III is a valuable tool in analytical chemistry for metal ion detection and quantification.
