Description:
2-Naphthalenesulfonic acid, 7,7′-(carbonyldiimino)bis[4-hydroxy-3-[(6-sulfo-2-naphthalenyl)azo]-, sodium salt, with CAS number 83763-79-5, is a complex organic compound characterized by its azo dye structure, which includes naphthalene and sulfonic acid functional groups. This compound typically exhibits vibrant coloration due to the presence of azo linkages, making it useful in various dye applications, particularly in textiles and paper. The sulfonic acid groups enhance its solubility in water, allowing for better application in aqueous solutions. Additionally, the presence of hydroxyl groups contributes to its reactivity and potential for further chemical modifications. As a sodium salt, it is likely to be more stable and easier to handle compared to its acid form. This compound may also exhibit properties such as UV absorption and potential biological activity, which can be relevant in fields like biochemistry and materials science. Safety and handling precautions should be observed, as with many azo compounds, due to potential toxicity and environmental concerns.
