Used as an intermediate in the synthesis of taurine (2-aminoethanesulfonic acid), which is widely applied in animal feed, pharmaceuticals, and dietary supplements as a promoter of growth, cardiovascular health, and antioxidant. Also utilized in the preparation of surfactants and detergents due to its ability to modify surface properties. Plays a role in organic synthesis for introducing sulfonate functional groups, enhancing water solubility of compounds. Employed in some pharmaceutical formulations as a buffering or stabilizing agent. Its reactivity makes it valuable in producing specialty chemicals for industrial and research applications.
