Used primarily in the dye and pigment industry, this chemical serves as an intermediate in the synthesis of azo dyes, which are widely employed in textiles, leather, and paper coloring. Its structure allows for effective binding to fibers, ensuring vibrant and long-lasting colors. Additionally, it finds application in the production of specialty chemicals and organic compounds, where its sulfonic acid group enhances solubility and reactivity. In research, it is utilized as a reagent for studying dyeing processes and developing new colorants with improved properties.
