This chemical is primarily used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes, which are widely employed in the textile industry for coloring fabrics. Its sulfonic acid groups enhance water solubility, making it valuable in formulations requiring stable and vibrant colors. Additionally, it serves as a dispersing agent in various industrial processes, helping to maintain the uniform distribution of particles in liquid media. In the paper industry, it is utilized to improve the brightness and quality of paper products. Its role in organic synthesis also extends to the preparation of other specialty chemicals, contributing to the development of advanced materials and coatings.
