Product Description

2,7-naphthalene disulfonic acid disodium salt

AI Product Description

*The following content is generated by AI and is for reference only.

2,7-Naphthalene Disulfonic Acid Disodium Salt is a vital industrial chemical derived from naphthalene, characterized by its high water solubility and stability. With the molecular formula C10H6Na2O6S2 and CAS Registry Number 845-96-9, this compound appears as a white to off-white crystalline powder or granules. It serves as a critical intermediate in various chemical synthesis pathways, particularly within the dyeing and textile industries. The presence of two sulfonate groups attached to the naphthalene ring at the 2 and 7 positions enhances its reactivity and ability to form stable complexes with metal ions, making it indispensable for producing specific azo dyes and pigments used in cotton, wool, and synthetic fiber coloring. Beyond textiles, this disodium salt finds extensive application in the pharmaceutical sector as a precursor for synthesizing active pharmaceutical ingredients (APIs) and drug delivery systems. Its unique structural properties allow it to act as a coupling agent or a modifier in polymer chemistry, improving the dispersibility and compatibility of additives in resin formulations. Furthermore, it is utilized in the manufacturing of surfactants and detergents, where it contributes to emulsification and cleaning efficiency. In the field of analytical chemistry, the compound is sometimes employed as a standard reference material due to its well-defined purity and consistent physical characteristics. The production process typically involves the sulfonation of naphthalene followed by neutralization with sodium hydroxide, ensuring the formation of the stable disodium salt. Safety protocols emphasize handling the substance with care, as it may cause mild irritation to skin and eyes upon direct contact. Proper storage in cool, dry environments away from incompatible oxidizing agents is recommended to maintain product integrity. As global demand for high-performance dyes and specialized polymers continues to rise, 2,7-naphthalene disulfonic acid disodium salt remains a cornerstone raw material, bridging the gap between basic petrochemical feedstocks and high-value finished goods across multiple sectors including agriculture, electronics, and environmental remediation technologies.
