Used as a buffering agent in biochemical and molecular biology applications, particularly in electrophoresis and chromatography, to maintain stable pH conditions. It is also employed in the preparation of zwitterionic buffers for protein purification and analysis, ensuring minimal interference with biological processes. Additionally, it finds use in the synthesis of surfactants and detergents due to its sulfonic acid group, which enhances solubility and stability in aqueous solutions. Its zwitterionic nature makes it suitable for stabilizing enzymes and proteins in various research and industrial processes.
