Used as a precursor in the synthesis of ionic liquids, particularly those with zwitterionic or betaine-like structures. Its sulfonate group enables water solubility and enhances compatibility with biological systems, making it suitable for applications in green chemistry, catalysis, and as a functional component in electrochemical systems. It is also employed in the development of biocompatible materials and in studies involving enzyme stabilization due to its ability to modulate polarity and ionic interactions in solution.
