Used as a key intermediate in the synthesis of taurine and other biologically active compounds. Serves in organic synthesis for introducing sulfonate functionalities, which can improve water solubility of molecules. Applied in the development of surfactants and detergents due to its polar sulfonate group. Also utilized in electroplating processes as an additive to enhance plating efficiency and surface finish. Shows utility in pharmaceutical formulations where sulfonated compounds are needed for stability or bioavailability.
