Used as an intermediate in the synthesis of dyes and pharmaceuticals, particularly in the development of sulfonamide-based drugs with antimicrobial properties. It also serves in analytical chemistry as a derivatizing agent for the detection of carbonyl compounds. Due to its polar nature, it finds use in modifying chromatographic behavior in HPLC applications. Additionally, it can act as a surfactant or emulsifier in specialized industrial processes requiring water-soluble sulfonated compounds.
