For businesses operating in the dye and pigment manufacturing sectors, securing a consistent and high-quality supply of critical intermediates is paramount. Sodium 2-naphthol-7-sulfonate, identified by CAS number 135-55-7, is one such compound, playing a vital role in the creation of numerous colorants. As a leading chemical manufacturer and supplier based in China, we are committed to being your premier source for this essential intermediate.
Why Sodium 2-Naphthol-7-Sulfonate is Indispensable
Sodium 2-naphthol-7-sulfonate is an organic chemical intermediate widely recognized for its application as a coupling component in the synthesis of azo dyes and certain organic pigments. Its chemical structure, a sulfonated derivative of 2-naphthol, provides the necessary reactivity and solubility to facilitate complex organic reactions. The 'sodium salt' form ensures good water solubility, which is a significant advantage in many industrial processes, especially in the textile and printing industries where aqueous dyeing and printing methods are common.
The performance of the final dye or pigment is directly correlated with the purity of the intermediate. Our Sodium 2-naphthol-7-sulfonate is produced to a minimum purity of 98%, ensuring that our clients can achieve consistent color strength, desired hues, and excellent fastness properties in their finished products. This reliability is crucial for maintaining product quality and customer satisfaction.
