Amino(imino)methanesulfonic acid is primarily used in biochemical research and industrial applications as a stabilizing agent and buffer. It is effective in maintaining pH levels in various chemical reactions, particularly in enzymatic studies where consistent pH is critical for accurate results. Additionally, it serves as a precursor in the synthesis of other sulfonic acid derivatives, which are valuable in the production of detergents, dyes, and pharmaceuticals. Its unique properties also make it suitable for use in electroplating solutions, where it helps improve the quality and adhesion of metal coatings.
