This chemical is primarily used as an intermediate in the synthesis of dyes and pigments. It plays a crucial role in the production of azo dyes, which are widely applied in the textile industry for coloring fabrics. Additionally, it is utilized in the preparation of certain specialty chemicals and organic compounds, particularly those requiring sulfonic acid groups for enhanced solubility or reactivity. Its nitration and sulfonation properties make it valuable in creating complex molecules for research and industrial applications.
