Sodium 2-naphthalenesulfonate (CAS: 532-02-5) is an aromatic sulfonate featuring a naphthalene ring system that provides a hydrophobic platform combined with strong water solubility from the sulfonate group. This white crystalline compound serves as a dispersing agent and wetting additive in dye baths, improving color uniformity and preventing dye aggregation on textiles. It functions as a concrete superplasticizer component and dispersant in construction chemicals, enhancing flow and reducing water demand. The compound also acts as an intermediate for naphthalene-based dyes, pigments, and specialty chemicals, and as a solubilizer in industrial formulations. Additional applications include electroplating baths, leather processing, and as a chemical intermediate for further sulfonation products. With its excellent solubility, thermal stability, and dispersing power, sodium 2-naphthalenesulfonate is a versatile processing aid across multiple industries.

– Textile Dyeing: Used as a dispersing and leveling agent in dye baths preventing dye aggregation and ensuring uniform shade development.
– Concrete Admixtures: Serves as a component in superplasticizer formulations improving workability and water reduction in cement systems.
– Chemical Intermediate: Applied in producing naphthalene-based dyes, pigments, and specialty aromatic compounds.
– Industrial Dispersion: Employed as a dispersant and wetting agent in pigment slurries, electroplating baths, and leather processing.
