Used as a buffer agent in biochemical and molecular biology research to maintain stable pH conditions during experiments. It is particularly useful in electrophoresis techniques, such as SDS-PAGE, for protein separation and analysis. Also employed in the preparation of zwitterionic buffers, which are essential for maintaining the stability and activity of proteins and enzymes in solution. Additionally, it serves as a precursor in the synthesis of other sulfonic acid derivatives, which have applications in detergents, surfactants, and industrial processes. Its zwitterionic nature makes it suitable for use in chromatography and other analytical methods where pH control is critical.
