Used as a zwitterionic surfactant in aqueous solutions, this compound stabilizes proteins and enzymes during purification and analysis, particularly in electrophoresis and mass spectrometry. Its sulfonate and pyridinium groups provide excellent water solubility and reduce nonspecific binding, making it ideal for biological sample preparation. It is also employed in buffer systems to maintain protein solubility and prevent aggregation without disrupting native structures. Additionally, it serves as a biocompatible additive in chromatography and capillary electrophoresis to minimize surface adsorption of biomolecules.
