China and India are the leading exporters of Sodium 2-naphthalenesulfonate, accounting for the majority of global shipments, while the United States, Germany, and South Korea represent the largest importers. Sodium 2-naphthalenesulfonate prices have remained relatively stable amid steady demand from dye, detergent, and construction chemical sectors. Export volumes from China have increased modestly over the past two years, while Indian exports have plateaued, and U.S. imports have shown consistent year-on-year growth.
Sodium 2-naphthalenesulfonate is a white to off-white crystalline solid, odorless and non-volatile, with a melting point typically above 300 °C (decomposes). It is an aromatic organic compound classified as a sulfonated naphthalene derivative and widely used as a chemical intermediate. Its primary industrial applications include serving as a precursor in the synthesis of azo dyes, pigments, and dye intermediates, particularly for textile and leather colorants. It is also employed in the formulation of dispersants for dyes, pesticides, and construction chemicals, and finds use in polymer manufacturing—especially as a comonomer or modifier in sulfonated polynaphthalene-based superplasticizers for concrete.
