Sulphonazo III sodium salt is an inorganic compound that readily dissolves in water. It possesses strong oxidizing properties and finds application in the production of certain coatings, including chrome yellow and chrome green. Additionally, this compound can be utilized for staining carbohydrates in microscopy, forming stable complexes in combination with potassium dichromate. Sulphonazo III sodium salt exhibits the ability to form stable complexes with carbon nanotubes and anions such as chloride. Its unique molecular structure allows for its concentration to be particularly high under low pH conditions and in the presence of transition metal ions. Furthermore, this compound demonstrates particle-like characteristics and exhibits an affinity for binding uronic acid molecules. Moreover, Sulphonazo III sodium salt can serve as a modifier or additive in non-aqueous electrolytes of secondary batteries.
