:2-Naphthol-3,6-disulfonic acid disodium salt
Description:
2-Naphthol-3,6-disulfonic acid disodium salt, with the CAS number 135-51-3, is an organic compound characterized by its sulfonic acid groups attached to a naphthalene ring. This compound is a disodium salt, indicating that it contains two sodium ions that balance the negative charges from the sulfonic acid groups. It is typically a white to light yellow crystalline powder that is soluble in water, making it useful in various aqueous applications. The presence of sulfonic acid groups imparts strong acidic properties, contributing to its reactivity and ability to form complexes with metal ions. This compound is often utilized in dye manufacturing, particularly in the production of azo dyes, and serves as a pH indicator due to its color-changing properties in different pH environments. Additionally, it may have applications in the textile industry and as a reagent in analytical chemistry. Safety data should be consulted for handling, as with all chemical substances, to ensure proper precautions are taken.

CAS:<p>Disodium 2-naphthol-3,6-disulfonate is a cationic surfactant that reacts with chloride ions to form a gel. It can be used as an inhibitor of corrosion and foaming in the oil industry. Disodium 2-naphthol-3,6-disulfonate has also been shown to have a linear response with fluorescence techniques when it interacts with metal ions. The kinetic data for this reaction is dependent on the concentration of chloride ions, which are generated by hydrochloric acid upon addition of water.</p>Formula:C10H6Na2O7S2Purity:Min. 97 Area-%Color and Shape:PowderMolecular weight:348.26 g/molDisodium 3-hydroxy-2,7-naphthalenedisulfonate
