Sulfanilic Acid (CAS 121-57-3) is a foundational chemical intermediate that plays an indispensable role in the global dye manufacturing industry. As a leading manufacturer and supplier from China, we understand the critical need for high-purity materials to achieve vibrant, stable, and consistent coloration in textiles, inks, and various other applications. Our commitment to producing Sulfanilic Acid with an assay of ≥99.0% ensures that our clients receive a product that meets the most stringent quality standards required for sophisticated dye synthesis.

The unique chemical structure of Sulfanilic Acid, an aromatic amine sulfonated at the para-position, makes it an ideal precursor for diazo coupling reactions. This reaction is the cornerstone of producing a vast array of azo dyes, which are known for their brilliant hues and diverse applications. From the deep blues and reds to vibrant yellows and greens, the palette enabled by this intermediate is extensive. Buyers looking to purchase Sulfanilic Acid for dye production often seek consistent quality and reliable supply, attributes that we, as a dedicated Chinese supplier, prioritize.

Beyond its primary use in azo dyes, Sulfanilic Acid also finds utility in the formulation of printing and dyeing auxiliaries. These chemicals are essential for optimizing the dyeing process, improving dye uptake, ensuring evenness, and enhancing color fastness. By providing a high-grade Sulfanilic Acid, we enable manufacturers of these auxiliaries to develop more effective and efficient products.
