Used primarily as a chiral derivatizing agent in analytical chemistry, this compound enables the separation and identification of enantiomers in complex mixtures through techniques like HPLC and capillary electrophoresis. Its sulfide-rich structure supports strong interactions with metal ions, making it useful in catalysis and sensor design for detecting trace metals in environmental and biological samples. Additionally, it serves as a synthetic intermediate in the preparation of bioactive molecules, particularly those targeting neurological and metabolic pathways. The quaternary ammonium group enhances solubility in aqueous media, facilitating its use in biochemical assays and drug delivery systems where membrane permeability and stability are critical.
