Used as an intermediate in the synthesis of taurine-based compounds, particularly in pharmaceuticals and nutritional supplements. It plays a role in the production of taurine analogs that are investigated for their antioxidant, neuroprotective, and anti-inflammatory properties. Also utilized in research settings to develop novel amino acid derivatives for biochemical studies. Its sulfonate group enhances water solubility, making it suitable for applications requiring high solubility in aqueous systems.
