Naphthol AS-BI-phosphate disodium salt (CAS 530-79-0)

Naphthol AS-BI phosphate disodium salt, also known as Naphthol AS-BI Phosphate, is a white, water-soluble powder with a melting point of approximately 250°C. It belongs to the naphthol phosphate family and serves as an anionic surfactant widely utilized in industrial and scientific fields. The chemical formula of Naphthol AS-BI phosphate disodium salt is C19H17Na2O7P. Its usage involves investigating protein and other biological molecule properties, as well as examining the structure and dynamics of biological systems. Moreover, it plays a role in nanoparticle synthesis and serves as a reagent in organic synthesis processes. The primary function of Naphthol AS-BI phosphate disodium salt as a surfactant is to lower the surface tension of aqueous solutions. This reduction in surface tension facilitates the formation of micelles, which are clusters of surfactant molecules that create a protective layer on the surface of aqueous solutions. This layer contributes to the stabilization of the solution and prevents the formation of foam or bubbles.
