Used primarily as an intermediate in the production of dyes and pigments, particularly for textiles and paper. It plays a key role in synthesizing reactive dyes, which are known for their strong bonding with fabric fibers, ensuring colorfastness and durability. Additionally, it is utilized in the manufacturing of certain agrochemicals, where it serves as a building block for herbicides and fungicides. Its sulfonate group enhances water solubility, making it suitable for applications requiring aqueous formulations.
