Used in the synthesis of dyes and pigments, particularly in the textile industry, to create vibrant and long-lasting colors on fabrics. Acts as an intermediate in the production of sulfonated compounds, which are essential in manufacturing detergents and surfactants due to their ability to reduce surface tension and improve cleaning efficiency. Also employed in the development of pharmaceuticals, where it serves as a building block for active ingredients in medications. Its sulfonate group enhances water solubility, making it valuable in formulations requiring improved bioavailability. Additionally, utilized in research and development for studying sulfonation reactions and their applications in organic chemistry.
